Defendant was convicted of three counts of selling heroin (§ 11501, Health & Saf. Code); allegations of two prior felony convictions were found to be true. He appeals from the judgment.
*758 To assist him in an extensive “buy” program in Los Angeles being conducted by the Los Angeles Police Department from July through December 1965, undercover Officer Limas used an informer named Joe. Joe, a narcotics user, was not employed by the police department, but was present at approximately 105 narcotic transactions, three of which constitute the within charges. The officer testified that he did not know Joe by any other name, did not serve any subpoena on him for his appearance at the trial or ask him to be a witness, does not know Joe’s whereabouts, never told him to make himself unavailable for court or to disappear, and never heard any other officer tell him to hide or not appear.
On August 30, 1965, Joe and Officer Limas went to the Saddle Rock Cafe; Joe went in alone and in a few minutes came out with defendant. Officer Limas gave $10 to defendant who handed him a purple balloon containing heroin which he took from his mouth. The next day the officer, who was alone, met defendant at Third and Hill; he asked him if he had a “half” and defendant told him to go to the Saddle Rock Cafe restroom. In the restroom Officer Limas said he wanted a “half” and handed defendant a $10 bill; defendant asked if the $10 bill he gave him yesterday was good and the officer said it was; then defendant took a white balloon containing heroin from his mouth and gave it to the officer. On September 2, 1965, Officer Limas and Joe met defendant on West Third Street. Joe asked defendant if he had a “half”; defendant answered in the affirmative. The officer then asked defendant for a “half” and handed him a $10 bill; defendant gave Officer Limas an orange balloon containing heroin which he took from his mouth.
Defendant testified that he never met Officer Limas until after he was arrested; he did not know Joe and he could not recall where he was at any of the above times. For the defense, Chavez testified that Joe was also known as Carlos Moreno; and Jones testified that Moreno came back from Arizona two weeks before the trial but did not know where he was.
Appellant argues that he was denied a fair trial because the prosecution was withheld until the informant was unavailable. He seeks to apply
People
v.
Kiihoa,
*759
In the absence of evidence that the People or the police sought to suppress the testimony of the informer or bring about his absence or disappearance, defendant cannot predicate error on the People’s failure to produce him.
(People
v.
White,
As to the delay in arresting defendant, the record shows that the information was filed on February 14, 1966, and that the last offense was committed on September 2, 1965. We know of no requirement that an accused be arrested at any specific time between the commission of the offense and the expiration of the time provided by the statute of limitations as to that particular crime.
(People
v.
Aguirre,
Defendant made the three sales to Officer Limas during a narcotic “buy” program conducted by undercover police officers in the Los Angeles area involving many purchases over a substantial period of time from sellers not previously known to the police; informers, although not necessarily employed by the police department, were used to ferret out peddlers. Joe, the informant herein, was present at more than 100 transactions. It is obvious that had Officer Limas arrested defendant on September 2, 1965, at the time of the third sale, he would have rendered useless his undercover status, destroyed the work of his informant, alerted other offenders and prevented further substantial police work. This kind of “buy” program has been approved by our courts as acceptable police practice; and the necessity for keeping the officer’s identity secret for a reasonable period of time has been held to be a legitimate basis for delaying the arrest of the individual wrongdoer while the officer is continuing his investigations.
(People v. Wilson,
Whatever delay occurred in the trial of the cause was largely the result of defendant’s own conduct. He requested and received numerous continuances which delayed the trial three months past the date on which it was originally set. Defendant entered his plea on February 10,1966, and the trial was set for March 31, 1966; further continuances at the defendant’s request delayed the trial until June 17, 1966. The cause was finally heard on June 21,1966.
In an Addendum To The Opening Brief filed by appellant he contends that the arrest is invalid because at the trial the police refused to identify the informer who “is the proximate cause of the crime being committed.” At no time did Officer Limas refuse to identify the informant. Without being questioned concerning the matter, the officer readily admitted that he was working with an “informer, Joe.” He testified that Joe is a narcotics user and is not employed by the police department, he does not know Joe by any other name and does not .know his whereabouts. The officer gave to defendant all of the information he had concerning the informer.
The judgment is affirmed.
Wood, P. J., and Fourt, J., concurred.
