Appellant contends that: (1) his warrantless arrest lacked probable cause; and (2) pre-trial identifications by two Commonwealth witnesses and two statements by him should have been suppressed because of an unnecessary delay in his arraignment. We disagree and, accordingly, affirm the judgment of sentence.
On November 16, 1976, at about 9:50 a. m., a Philadelphia policeman responding to a disorderly crowd complaint saw appellant shouting and carrying a large radio which he was playing loudly. The officer approached appellant, took him to the patrol car, and requested identification. The officer then checked appellant’s name through the National Crime Information Center (NCIC), 1 which reported that appellant was wanted on an outstanding arrest warrant and a juvenile detainer. Relying upon that information, the officer arrested appellant and took him to a nearby police station where the officer again checked the NCIC report, and received the same results. 2 Subsequently, the officer noticed that appellant had picked up a wanted poster bearing artists’ sketches of three suspects in the robbery of a bar on October 25, 1976. After appellant stated that he knew two of the suspects, the officer compared the third composite sketch and printed description to appellant. Finding a similarity, the officer arranged to have appellant transported to another police station where detectives were investigating the robbery.
Appellant arrived at the second station at about 1:30 p. m. and was informed that he was a suspect in the robbery. He *285 immediately requested a face-to-face confrontation with the witnesses and stated that he did not wish to wait for a line-up. A detective explained the nature of the charges and gave him his Miranda warnings at approximately 2:00 p. m. Appellant denied involvement and reiterated his desire for an immediate confrontation. The detective then told appellant that he had a right to a line-up and again reminded him of his right to free counsel. After declining representation and insisting upon a show-up, appellant signed a waiver form at 2:10 p. m. At approximately 3:45 p. m., Jaqueline Hutchins, a bar patron, arrived and identified appellant as one of the robbers. Following that identification, the police took a photograph of appellant. Shortly thereafter, at 4:20 p. m., another detective administered Miranda warnings and obtained an unsigned statement from appellant. The questioning ended at 4:45 p. m. At about 5:00 p. m., Theodore Chester, another patron, selected appellant’s picture from an array of eight to ten pictures. From 4:45 p. m. to 6:00 p. m., appellant was in a holding area where he ate a meal. Then, after the detectives administered Miranda warnings for a third time, appellant gave a statement until 7:00 p. m. That statement, which appellant read aloud and signed, repeated, with only minor variation, the details of the prior unsigned statement. Appellant was arraigned shortly thereafter. At appellant’s nonjury trial, the Commonwealth introduced, inter alia, the testimony of Ms. Hutchins and Mr. Chester, appellant’s statements, and evidence seized from appellant’s home pursuant to a search warrant. Appellant was convicted of attempted murder, robbery, criminal conspiracy, simple and aggravated assault, possession of an instrument of crime, and carrying a firearm in public. After the denial of post-verdict motions and imposition of sentence, appellant brought this appeal.
I.
Appellant contends that his warrantless arrest lacked probable cause. We disagree. “[T]he cases uniformly recognize that NCIC printouts are reliable enough to form the
*286
basis of the reasonable belief which is needed to establish probable cause for arrest.”
United States v. McDonald,
Appellant argues, however, that his arrest was unlawful because it was based upon inaccurate information from the NCIC computer, and that all subsequently acquired evidence was tainted by the illegal arrest. In particular, appellant contends that the NCIC computer failed to show that the arrest warrant and juvenile detainer had been satisfied four days earlier, and that there were no active warrants or detainers to support his arrest. We diságree. Probable cause for a warrantless arrest must be determined on the basis of the knowledge of the arresting officer at the time of arrest.
See, e. g., Commonwealth v. Mackie,
II.
Appellant next contends that the pre-trial identifications by two Commonwealth witnesses and his two inculpatory statements should have been suppressed because the delay between his arrest and arraignment violated Pa.R. Crim.P. 130 and
Commonwealth v. Futch,
Judgment of sentence affirmed.
Notes
. The NCIC maintains a nationwide computer system on stolen property and persons wanted on outstanding warrants.
. Sometime after the arrest, the police learned that the NCIC computer was incorrect because the outstanding arrest warrant and juvenile detainer had been satisfied four days before the arrest. Appellant was not, in fact, wanted on any active warrants or detainers.
. On the present record, we hold that the police conduct was not unreasonable.
Compare Childress v. United States, supra
(arrest valid, four-day-old inaccuracy),
and State v. Cross,
. Appellant contends also that he was “arrested” on the robbery and related charges while detained at the police station on the warrant violations and that his “arrest” lacked probable cause because it was based solely on appellant’s similarity to a composite sketch. This contention is patently frivolous. First, appellant was arrested on the street on the basis of the NCIC information.
See Commonwealth v. Marabel,
. Appellant was arrested before May 16, 1977, the effective date of
Commonwealth v. Davenport,
. Particularly, the delay from 2:10 p. m., when appellant signed the waiver, until 3:45 p. m., when the one-on-one confrontation occurred, is attributable solely to appellant’s request for identification by the witnesses of the robbery.
. Appellant raises three other contentions which we note here and reject.
Appellant argues that the lower court should have suppressed the one-on-one identification by Ms. Hutchins because appellant was not represented by counsel at the confrontation. Although one-on-one confrontations have been criticized, see, e. g., Commonwealth v. Fant,480 Pa. 586 , 590-91,391 A.2d 1040 , 1042-3 (1978), the lower court did not err in denying appellant’s motion to suppress. Appellant requested and then insisted on an immediate one-on-one confrontation. He was aware of the charges made against him, advised of his right to free counsel, and offered an opportunity to participate in a line-up. Nevertheless, he declined representation by counsel and signed a waiver form before the confrontation. Under these circumstances, appellant’s contention is meritless. See Commonwealth v. Jones,220 Pa.Super. 214 , 217,283 A.2d 707 , 708 (1971).
Appellant next contends that the lower court should have suppressed the identification of his photograph by Mr. Chester because it also was conducted in the absence of counsel. Although appellant had a right to be represented at the post-arrest photographic display, Commonwealth v. Whiting,439 Pa. 205 , 209,266 A.2d 738 , 739 (1970), “ ‘[ajppellant may not now complain of the failure to suppress evidence which his own counsel elicited [on cross-examination] at trial.’ ” Commonwealth v. Ransome,485 Pa. 490 , 497,402 A.2d 1379 , 1383 (1979) (quoting Commonwealth v. Brown,462 Pa. 578 , 589,342 A.2d 84 , 89 (1975)) (evidence of uncounseled line-up).
Appellant also argues that the identifications and statements should have been suppressed as the fruits of the allegedly illegal arrest, one-on-one confrontation, and/or photographic display. Finding no defect in those procedures, we need not address that issue.
