A jury found Enrique Perez guilty on four counts of first degree robbery (Pen. Code, § 211a). He admitted two prior first degree robbery convictions. A motion for a new trial was denied, and he appeals from the judgment, contending that evidence of a prior robbery was improperly admitted; that the evidence is insufficient to support his conviction on counts 3 and 4; and that he did not waive *617his federal constitutional privilege against self-incrimination as to two of the robberies charged by testifying on direct examination as to the other robberies charged and therefore error was committed of the type condemned in Griffin v. California, 380 U.S. 609 [14 L.Ed.2d 106, 85 S.Ct. 1229].
Count 1 (January 3,1965, robbery at the Viking Club):
About 9 p.m. on January 3, 1965, two men entered the Viking Club in Sacramento. One of them was armed with a revolver and had a glove over his mouth. After informing the bartender, Frederick Fauble, that “this was a holdup,’' the robbers took $325, a Bankamerieard, and a Shell credit card. Defendant’s fingerprints were found on a cigar box that was knocked off a shelf by one of the robbers.
Defendant admitted using the stolen Bankamerieard to make various purchases and signing Bauble’s name to the sales slips. He testified that one Robert Gomes gave him the card in early January after trying to sell it to him. Defendant denied having been in the Viking Club on the night of the robbery and testified that he was with his brother, Miguel, and a friend, Joseph Rosales, when the robbery was committed. His alibi was supported by testimony of Miguel and Mrs. Joseph Rosales.
Count 2 (January 15,1965, robbery at the Corner Market):
About 7 p.m. on January 15, 1965, David Perez (who is not a relative of defendant) and a second man entered the Corner Market in Sacramento. Each man carried a gun and held a glove or cloth over his face covering his nose and mouth. The men demanded money from Mr. and Mrs. James Monahan, who operated the store, and took from them about $69 and a radio. Mr. and Mrs. Monahan identified defendant at the trial as the second robber. They had a momentary full face view of him on one occasion during the robbery when he dropped the covering from his face.
Defendant testified that he was at his home when the Monahans were robbed, and his alibi was supported by testimony of his brother Miguel and his mother.
Counts 3 and 4 (January 13, 1965, robberies at Ralph’s Bar):
About 1:15 a.m. on January 13, 1965, David Perez and two other men entered Ralph’s Bar, which was in the same general neighborhood as the Corner Market. One of the men carried a revolver. David Perez wore a mask, and one of his *618companions used a handkerchief as a mask. Ray Biner, the bartender, and Eli Dragash, a patron who was partially blind, were in the bar. The robbers took $6 from Dragash and the money in the cash register. Biner and Dragash were unable to see the faces of the men who accompanied David Perez but described the height and weight of one of his companions, and the jury, of course, had an opportunity to observe defendant.
Defendant was with David Perez at the apartment of David’s sister, Sylvia Moreno, about three blocks from Ralph’s Bar at 1 or 1:30 a.m. on January 13, 1965, which was just before or after the robbery at that bar. The weapon used by defendant at the Corner Market robbery, clothing worn by him at that robbery, the stolen radio, and a coat worn by one of David Perez’s companions at the Ralph’s Bar robberies were found at Mrs. Moreno’s apartment.
Prior Collateral Robbery
At 6 :45 p.m. on November 10, 1964, two men entered the Modern Variety Store in Sacramento. Both wore stockings that covered their faces, and one carried a rifle. William George, the owner of the store, was working there that evening. The robbers took currency from the cash register, money orders, and a cheek protector. Some of the stolen money orders were later negotiated.
Items stolen in the Modern Variety Store robbery were left by defendant and one David Hunt at the home of an acquaintance. Defendant stated at that time that they got the items in a holdup in Sacramento.
Defendant objected at the trial to the admission of the evidence of the prior robbery, and the trial court, before admitting the evidence, held proceedings outside the jury’s presence at which the court was informed what evidence would be introduced and heard arguments on the matter.
“ It is settled in this state that except when it shows merely criminal disposition, evidence which tends logically and by reasonable inference to establish any fact material for the prosecution, or to overcome any material fact sought to be proved by the defense, is admissible although it may connect the accused with an offense not included in the charge.” (People v. Henderson, 60 Cal.2d 482, 494-495 [35 Cal.Rptr. 77, 386 P.2d 677] ; People v. Woods, 35 Cal.2d 504, 509 [218 P.2d 981] ; see also People v. Coefield, 37 Cal.2d 865, 869 [236 P.2d 570].) Here the evidence of the prior robbery was relevant on the issue of the identity of defendant as a perpetrator of the robberies charged. The evidence of the prior *619robbery disclosed a plan, pattern, and modus operandi similar in many respects to those used in the robberies charged. In the prior offense, as in each of the offenses charged, the place robbed was a business establishment in Sacramento, the robbery was committed during the evening or early morning hours, two or three men participated in the robbery, one or more of the robbers wore a mask, a gun was used in committing the robbery, and no victim was physically injured. It further appears that in the prior robbery and all the robberies charged, except those at Ralph’s Bar, property in addition to money was taken, that the Bankamerieard taken in the Viking Club robbery was later used by defendant, and that the money orders taken at the prior robbery were likewise later used apparently by one of the robbers.
In view of the striking similarities between the prior offense and the ones charged we are satisfied that the trial court did not abuse its discretion in admitting the evidence. (People v. Adamson, 225 Cal.App.2d 74, 78 et seq [36 Cal.Rptr. 894]; People v. Renchie, 217 Cal.App.2d 560, 563 [31 Cal.Rptr. 694]; People v. McCarty, 164 Cal.App.2d 322, 325-327 [330 P.2d 484].) There were factual differences between the prior robbery and the ones charged, such as that at the robberies at the Viking Club and Ralph’s Bar, unlike the prior robbery, the victims were made to lie on the floor, but it was, of course, unnecessary to prove the prior offense identical in every detail with the crimes charged in order to render evidence of the prior offense admissible. (People v. Rosoto, 58 Cal.2d 304, 330 [23 Cal.Rptr. 779, 373 P.2d 867]; People v. Renchie, supra, 217 Cal.App.2d 560, 563.)
We are satisfied that the evidence is sufficient to support the jury’s verdict on each count.
As we have seen, on direct examination defendant gave an alibi with respect to the robberies charged in counts 1 and 2. He did not refer on direct examination to the robberies charged in counts 3 and 4 or the collateral robbery. On cross-examination the prosecution asked a question directed to show that defendant was with David Perez a few moments after the robberies charged in counts 3 and 4, and an objection on the ground that the question was beyond the scope of direct examination was sustained. No questions were asked on cross-examination regarding the collateral robbery. In the closing argument the prosecution made comments on defendant’s failure to explain or deny the evidence of his guilt as to counts 3 and 4. The trial court gave an instruction permitting the jury to draw an inference adverse to defendant from his failure to *620explain or deny facts within his knowledge.1 [See fn. 2] After the verdict was returned the United States Supreme Court rendered its decision in Griffin v. California, supra, 380 U.S. 609, and defendant argues that under that decision the argument and instruction were improper.2
In People v. Ing, ante, pp. 603, 609-610 [55 Cal.Rptr. 902, 422 P.2d 590], we stated that Griffin v. California, supra, 380 U.S. 609, “held that the California constitutional provision permitting comment on the failure of the defendant to testify (Cal. Const., art. I, § 13) violated the Fifth Amendment privilege against self-incrimination made applicable to the states in Malloy v. Hogan, 378 U.S. 1 [12 L.Ed.2d 653, 84 S.Ct. 1489], Griffin further declared that ‘the same standards must determine whether an accused’s silence in either a federal or state proceeding is justified. ’ See also Malloy v. Hogan, supra, at p. 11.) In Griffin the defendant had not taken the stand, whereas here defendant testified in his own behalf, and it is necessary to consider to what extent he thereby waived his privilege against self-incrimination.
“Under federal decisions a defendant who takes the stand and testifies in his own behalf waives his Fifth Amendment privilege against self-incrimination at least to the extent of the scope of relevant cross-examination. (Johnson v. United States, 318 U S. 189, 195 [87 L.Ed. 704, 63 S.Ct. 549]; Caminetti v. United States, 242 U.S. 470, 494 [61 L.Ed. 442, 37 S. Ct. 192]; Powers v. United States, 223 U.S. 303, 314-316 [56 L. Ed. 448, 32 S.Ct. 281]; Sawyer v. United States, 202 U.S. 150, *621165-166 [50 L.Ed. 972, 26 S.Ct. 575]; Fitzpatrick v. United States, 178 U.S. 304, 314-316 [44 L.Ed. 1078, 20 S.Ct. 944]; Ziegler v. United States, 174 F.2d 439, 446-447; Branch v. United States, 171 F.2d 337, 338; Carter v. United States, 19 F.2d 431, 434; see Brown v. United States, 356 U.S. 148,154 [2 L.Ed.2d 589, 78 S.Ct. 622, 72 A.L.R.2d 818]; DeRose v. United States, 315 F.2d 482, 487.) It matters not that the defendant’s answer on cross-examination might tend to establish his guilt of a collateral offense for which he could still be prosecuted. (Johnson v. United States, supra, 318 U.S. 189, 192 et seq.; Carpenter v. United States, 264 F.2d 565, 569; see McCormick on Evidence (1954), p. 275.) ”
As we have seen, on direct examination defendant testified to an alibi with respect to counts 1 and 2 and thus in effect denied the offenses charged in those counts. Cross-examination as to the collateral offense, which disclosed a plan, pattern, and modus operandi similar in many respects to those charged, would have been proper. (People v. Ing, supra, ante, p. 612, and authorities cited therein.) Cross-examination as to the robberies charged in counts 3 and 4 likewise would have been proper. Those robberies, like the collateral robbery, disclosed a plan, pattern, and modus operandi similar in many respects to those charged in counts 1 and 2.
The fact that defendant was then on trial for the robberies charged in counts 3 and 4 does not preclude a determination that the waiver extends to those offenses. To hold otherwise would permit a defendant to withdraw from the crossfire of interrogation before the reliability of his testimony has been fully tested. It is also of importance that the reasons advanced for the privilege are decisively less persuasive when applied to disclosures requested after the accused has voluntarily taken the stand. (See 8 Wigmore on Evidence (McNaughton rev. 1961) § 2276, p. 462.)
In our opinion it was not a violation of the federal constitutional privilege against self-incrimination for the prosecutor to argue and the court to instruct that an inference unfavorable to defendant could be drawn from his failure to explain or deny facts within his knowledge relating to counts 3 and 4 or to the collateral offense. The trial court’s instruction was general in terms and permitted the jury to draw an inference unfavorable to defendant from his failure to deny or explain any matters within his knowledge, but no claim is made that there was any additional matter beyond the scope of relevant cross-examination that defendant failed to explain or deny.
*622No contention is made that the argument or instruction violated the state constitutional privilege against self-incrimination (Cal. Const., art I, § 13 ) , nor could such a contention properly be made in the present case A defendant by testifying in his own behalf waives his state constitutional privilege against self-incrimination to the extent of the permissible scope of cross-examination (People v. Ing, supra, ante, p. 611, and authorities cited therein). Cross-examination with respect to the collateral offense would have been proper under California decisions (People v. Ing, supra, ante, pp. 611-612, and authorities cited therein). Cross-examination as to the robberies charged in counts 3 and 4, which, as we have seen, disclosed a plan, pattern, and modus operandi similar in many respects to those charged in counts 1 and 2, likewise would have been proper.
The judgment is affirmed.
Traynor, C. J., McComb, J., Tobriner, J., and Mosk, J., concurred
The instruction read: "It is a constitutional right of a defendant in a criminal trial that he may not be compelled to testify. Thus, whether or not he does testify rests entirely in his own decision. As to any evidence or facts against him which the defendant can reasonably be expected to deny or explain because of facts within his knowledge, if he does not testify or if, though he does testify, he fails to deny or explain such evidence, the jury may take that failure into consideration as tending to indicate the truth of such evidence and as indicating that among the inferences that may be reasonably drawn therefrom those unfavorable to the defendant are the more probable. In this connection, however, it should be noted that if a defendant does not have the knowledge that he would need to deny or to explain any certain evidence against him, it would be unreasonable to draw an inference unfavorable to him because of his failure to deny or explain such evidence. The failure of a defendant to deny or explain evidence against him does not create a presumption of guilt or by itself warrant an inference of guilt, nor does it relieve the prosecution of its burden of proving every essential element of the crime and the guilt of the defendant beyond a reasonable doubt. ’ ’
The Griffin rule is applicable to cases pending on direct appeal at the time it was announced. (See Tehan v. Shott, 382 U.S. 406, 409, fn. 3 [15 L.Ed.2d 453, 86 S.Ct. 459]; Johnson v. New Jersey, 384 U.S. 719, 732 [16 L.Ed.2d 882, 86 S.Ct. 1772].)
