Defendant was convicted in a jury trial of theft in the first degree, assault in the second degree, robbery in the third degree and unauthorized use of a vehicle. He appeals, assigning as error (1) denial of his motion for a directed verdict of acquittal for robbery, (2) entering of a separate conviction for robbery, and (3) entering of a separate conviction for unauthorized use of a vehicle.1
Late in the evening of October 25, 1976, defendant and another person were accosted by a Clackamas County deputy sheriff while they were apparently in the act of stealing a vehicle. The officer engaged in a scuffle with the other person over possession of the officer’s service revolver. During the struggle defendant stabbed the officer twice and then grabbed him by the hair, held an object to his throat and said, "Let go of the gun or I’ll cut it,” or "I’ll slit it.” After being struck a third time, the officer lost control of the revolver. The two assailants made their escape from the scene in the officer’s patrol car, taking the gun with them.
On the first assignment of error defendant argues that there was insufficient evidence to show intent to commit theft of the revolver, which was the theft element in the robbery charge, because the evidence suggested that defendant’s original and continuing intent was to steal a car. He asserts that his actions were intended only to disarm the officer and to escape and that the intent to disarm excluded intent to commit theft of the gun.
The crime of robbery does not require an actual taking of property, but only intent to commit theft, for *766"repression of violence is the principal reason for being guilty of robbery.” Commentary, Oregon Criminal Code of 1971,190 (1975 ed). The requisite intent under the robbery statute2 is derived from the theft statute3 and the definitions of theft.4 Intent to commit theft is present where there is intent to dispose of property "under such circumstances as to render it unlikely that an owner will recover such property.” ORS 164.005(2)(b).
As stated in State v. Gibson, 36 Or App 111, 115, 583 P2d 584, rev den 285 Or 319 (1978),
"[T]he issue is not whether we believe defendant guilty beyond a reasonable doubt but whether the evidence was sufficient for the trier of fact so to find. State v. Krummacher, 269 Or 125, 137-38, 523 P2d 1009 (1974); State v. Zauner, 250 Or 105, 110, 441 P2d 85 (1968).”
In State v. Mack, 31 Or App 59, 569 P2d 624 (1977), we held that for purposes of determining commission of theft, intent permanently to deprive the owner of *767possession of property could be inferred from the circumstances surrounding the act.
From the circumstances of the episode, an inference could reasonably have been drawn by the jury that the deputy sheriff was unlikely to recover his revolver after the violent attempt to disarm him and the escape. The revolver was not left behind at the scene of the incident, and a witness testified that he saw the gun later that evening when defendant and a co-defendant were trying to operate the jammed mechanism. Next morning the witness brought the gun to the police and assisted in the arrest of defendant. The question was properly submitted to the jury.
On the second assignment of error, the state concedes error in the failure to merge the convictions for robbery and assault. See State v. Steele, 33 Or App 491, 497, 577 P2d 524, rev den 285 Or 195 (1978).
As to defendant’s third assignment, the conviction for unauthorized use of a vehicle was not required to be merged with that for the robbery or assault, because the unauthorized use charge was not encompassed by either of those charges. See State v. Dinkel, 34 Or App 375, 392, 579 P2d 245, rev den 285 Or 195 (1978). Moreover, this was not a "single criminal episode with a single criminal objective.” State v. Cloutier, 286 Or 579, 597, 596 P2d 1278 (1979). Defendant’s conduct in committing the robbery and assault was not "directed to the accomplishment”5 of unauthorized use of the vehicle, nor was the reverse true.
Affirmed in part, reversed in part and remanded for entry of a judgment merging the robbery and assault convictions.
Defendant was charged under two indictments. The first was for theft in the first degree. The second contained counts of attempted murder, assault in the second degree, robbery in the first degree and unauthorized use of a vehicle. The cases were consolidated for trial. The trial court merged the convictions for robbery, assault and unauthorized use in sentencing defendant on the assault charge.

ORS 164.015 provides in pertinent part:

ORS 164.005(2):
" 'Deprive another of property’ or 'deprive’ means to:
