Virgilio Encarnación, appellant, was accused and convicted by a court without a. jury of possession of heroin. He waived his right to trial by jury,, after the trial judge explained to him in detail the nature of the jury and the greater protection of his rights which the institution of the *911jury provides. He was sentenced to serve from six to ten years in the penitentiary.
After his case was referred on appeal to the Legal Aid Society, the latter informed that it did not find any errors to assign. It indicated that the doctrine established in People v. Márquez Estrada, 93 P.R.R. 790 (1966), was not applicable.
The evidence revealed that appellant was taken by surprise in Muñoz Rivera Street of the town of Carolina, behind a warehouse, while he was holding the right hand of one José Julián with one hand, and with the other hand he was holding a cap, at the same time that another individual was injecting José Julián with a hypodermic needle attached to a syringe. When they were taken by surprise, they fled but the police seized the cap and the other material which appellant had dropped. It was stipulated that the chemist would testify that he submitted this evidence to analysis, and it yielded positive results of heroin. Appellant testified that on the day and time in which it is alleged that the facts occurred, he was at another place in a restaurant.
The trial judge denied the motion for reconsideration of appellant’s judgment of conviction because he concluded that the Márquez case, supra, was not applicable because it does not appear from the stipulation of the case at bar, as in Márquez, supra, the amount of heroin which was seized in the cap. The hearing of this case was held on December 14, 1965, that is, the day before the date of our decision in Márquez, supra.
Appellant sets forth on his own right that:
(1) the trial court erred in accepting the stipulation that the policeman Carrasquillo gave to Sergeant Cardona the aforesaid seized evidence, and the latter returned it to the former two days later, and that the latter took it to general headquarters to the chemist Vázquez, and that when *912it-was analyzed by -the-latter i-t -yielded positive-results:.of heroin. He argues that there is no guarantee that the articles which were analyzed were' -the same ones which' were-seized. On cross-examination, of policeman Carrasquillo, the identity ON -the evidence" seized "and analyzed was established. The Marquez case, supra, is- not applicable-1 because' the record reveals that appellant acted jointly with another person in injecting a-.third- .'person,!.sóí that1-, when- the cap and hypodermic needle used in the: aforesaid act in this- case were seized,- and when'their , chemical test revealed, that they . contained heroin, it. is. obvious that when ,the; three persons ip question .were; taken by surprise by the police, appellant .and his’ companion- ¡possessed ah . amount .of .heroin susceptible of being-used as ..a: narcotic drug;
'-..(2) in giving-'credit to .policeman Carrasquillo’s testimony,-' for he. testified that' appellant was applying a tour-nD quet.to José Julian’s right arm, and .on. Cross-examination, he stated-that-he-whs holding his hand but was- not applying .a tourniquet. The record reveals that what Carrasquillo 'testified was that appellant was holding José Julián’s hand, “as if he were applying, a tourniquet”; ■ .
(3) in-.accepting as good that appellant, was arrested by-various policemen, without a warrant of arrest, six days after the facts-.occurred, and 'the complainant police officer was not among; them. As the Solicitor- General indicates, in view of the fqct that heroin was found in ..the cap and of the ..other circumstances of the case, .the police had grounds to believe that appellant had committed a felony, and therefore they could arrest him without a previous; warrant of arrest. Rule 11(c). of the Rules of Criminal Procedure.
The judgment rendered in. this case by the Superior Court, San Juan Part, on December 20, 1966, will be affirmed'.'
