On February 16, 1977, appellant Vertcell Sabb was found guilty by a jury of the crimes of simple assault, possession of an instrument of crime, involuntary deviate sexual intercourse, and rape. 1 Post trial motions were argued and denied and a sentence of four to twelve years imprisonment was imposed. On this direct appeal, appellant assigns as error various rulings of the court below as well as the ineffectiveness of his trial counsel. We find his contentions without merit and will therefore affirm.
Facts adduced at trial established the following: At approximately 3:15 A.M. on July 18, 1976, the complainant, a young artist, was entering her apartment at 437 South Street in Philadelphia. As she unlocked the door to the building and turned to relatch it, a man forced his way in with a knife and told her to shut up. The victim stepped back a pace, put up her hands, and inquired, “What do you want? Money?”, to which her assailant replied, “Don’t say a word or you’ll be cut.” At this point, the intruder pulled the victim’s hat, sporting a wide brim, over her eyes, and forced her onto the hallway floor where he raped her. Following this, he pulled up her tee-shirt and helcT the knife against her stomach for several seconds, and then fled. Throughout the ordeal, the intruder repeated the words, “Shut up” in a low, whispered tone with a definite rhythm or cadence described by the complainant as “marked — you could almost count, one, two, three, four, five in between his words.”
The complainant ran to her room, immediately called the police, and provided them with a description of the assailant. Responding to the call was Officer Michael Lutz of the *211 Philadelphia Police Department. At 3:50 A.M. that same morning, based upon the victim’s description, he arrested appellant and another individual in front of Pat’s Steaks, an establishment located at 6th and Catherine Streets, three and one-half blocks distant from the scene of the rape. Lutz transported the two suspects to Philadelphia General Hospital, where the victim was by that time being treated. When confronted with these two individuals, she immediately discounted the other male arrested and, after looking at appellant and hearing his voice, stated she was “ninety percent sure” he was the rapist. About an hour and a half later “when [she] had time to calm down a bit and clear [her] head and think of the face and the build” she became one hundred percent certain it was appellant.
Tests at the hospital showed the presence of sperm in the victim’s vagina. Similarly, chemical tests of the underwear appellant was wearing at the time of his arrest revealed the presence of seminal stains and sperm.
The defense was alibi. Appellant presented testimony suggesting that sometime before 2:00 A.M. on July 18, 1976, he visited his girlfriend, Gloria Merritt, at her home at 511 South Fifth Street. Miss Merritt was, at that time, experiencing a numbness of her legs, whereupon appellant suggested she go to the hospital. Appellant’s father, Emanuel Jackson, agreed to drive them to Pennsylvania Hospital, (8th and Spruce Streets) where the trio arrived sometime between 1:30 A.M. and 2:00 A.M. Appellant sat near the emergency room receptionist’s desk, conversing with several individuals, while Miss Merritt was treated by a doctor. Shortly after 3:00 A.M., the examination completed, Miss Merritt and appellant left the hospital and proceeded on foot to Pat’s Steaks, a distance of some eight blocks. Appellant had only sufficient time to purchase a sandwich before the police arrived and placed him under arrest at 3:50 A.M. 2

Appellant first contends the police lacked probable cause to arrest him. The test is well-settled. In determining the presence of probable cause, the crucial test is whether there were facts available at the time of the initial apprehension which would justify a man of reasonable caution in the belief that a crime had been committed and that the individual arrested was the probable perpetrator.
Commonwealth v. Wilder,
In the instant case, the description supplied by the victim to the police was as follows: Negro male,
5'
7", 130 lbs., wearing red and yellow plaid shirt, dark pants, small mustache, black, horn-rimmed glasses. Appellant, in large measure matching this description, was arrested less than one-half hour following the rape and only three and one-half blocks distant therefrom. This case thus closely resembles those where our courts have found probable cause based upon a very detailed description or a description coupled with circumstances. See, e. g.
Commonwealth v. Powers,
Appellant next contends it was error for the court to admit a police photograph of him showing the so-called “Bertillon” information of his height and weight. 3 Apparently, appellant does not object to the introduction of the photograph itself 4 but rather to the hearsay nature of the height and weight measurements at the time of arrest, included in the bottom of the picture. Detective Shubert, the officer who directed the investigation and through whom the photograph and accompanying measurements were introduced, testified he did not himself calculate the measurements of appellant and was not present when they were taken. Since the photograph was introduced by the Commonwealth for the purpose of establishing appellant’s height and weight at the time of arrest, we agree with appellant, and the Commonwealth concedes, that the information contained in the bottom of the picture is hearsay and thus inadmissible unless falling into a recognized exception. We think the official statement exception provides the appropriate doorway to admissibility:
The policy behind this exception [is] that of avoiding the inconvenience to and disruption of public affairs by requiring public officials to appear in court . . .. For a document to be admissible under the official statement exception “it is necessary that the evidence show that it was prepared pursuant to an official duty.” Githens, Rexsamer & Co. v. Wildstein,428 Pa. 201 , 205,236 A.2d 792 , 795 (1968); see V Wigmore, Evidence § 1630, et seq. (3d ed. 1940).

Commonwealth v. Slider,
Appellant next assigns as error the admission of hospital records showing the presence of sperm in the victim. We have previously decided this identical issue in favor of the record’s admissibility.
Commonwealth v. Campbell,
Appellant next contends the court improperly restricted his counsel’s cross-examination of Commonwealth witnesses on two occasions. Preliminarily, we note that the scope and limits of cross-examination are within the discretion of the trial judge and will. not be reversed in the absence of a clear abuse of that discretion or an error in law.
Commonwealth v. Greene,
Appellant also raised two instances of alleged ineffectiveness of his trial counsel. 5
It is by now axiomatic that the test for evaluating a claim of ineffective assistance of counsel is whether the record supports a conclusion that the particular course chosen by counsel had some reasonable basis designed to effectuate his client’s interests. Commonwealth ex rel. Washington v. Maroney,427 Pa. 599 ,235 A.2d 349 (1967). In making this assessment we are not to employ a hindsight evaluation to determine whether other alternatives may have been more reasonable, Washington v. Maroney, supra, but whether there was a reasonable basis for the course of action actually selected. Commonwealth v. Hosack,485 Pa. 128 ,401 A.2d 327 , (1979); Commonwealth v. O'Neal Weathers El,485 Pa. 28 ,400 A.2d 1295 (1979); Commonwealth v. Treftz,485 Pa. 297 ,401 A.2d 1325 (1979); Commonwealth v. Williams,485 Pa. 137 ,401 A.2d 331 (1979); Commonwealth v. Tome,484 Pa. 261 -265,398 A.2d 1369 , 1371-72 (1979); Commonwealth v. Betrand,484 Pa. 511 ,399 A.2d 682 (1979); Commonwealth v. Perrin,484 Pa. 188 ,398 A.2d 1007 , (1979); Commonwealth v. Ray,483 Pa. 377 ,396 A.2d 1218 (1979); Commonwealth v. Yocham,483 Pa. 478 ,397 A.2d 766 (1979); Commonwealth v. Chumley,482 Pa. 625 ,394 A.2d 497 (1978); Commonwealth v. Coleman,482 Pa. 581 ,394 A.2d 474 (1978); Commonwealth v. Sisco,482 Pa. 459 ,393 A.2d 1197 (1978). If a reasonable basis for counsel’s trial strategy decision exists, that decision is imputed to the client. Common *218 wealth v. Sullivan,450 Pa. 273 ,299 A.2d 608 , cert. denied,412 U.S. 923 ,93 S.Ct. 2745 ,37 L.Ed.2d 150 (1973). Commonwealth v. Musi,486 Pa. 102 , at 107,404 A.2d 378 , at 380 (1979).
Appellant argues his counsel’s cross-examination of the complainant as to her identification of him was so scant and lacking in depth as to render her assistance ineffective. This contention is simply not supported by the record. Our review indicates counsel cross-examined the victim as to the lighting at the crime scene, N.T. 2/8/77, pp. 32-35, 67; her description of the assailant, pp. 37-44; the confrontation at the hospital and the discrepancies between appellant’s appearance and that of the rapist, pp. 47-55, 69; and the circumstances under which she became “one hundred percent” sure appellant was the rapist, pp. 57-8. This full, probing cross-examination cannot be deemed ineffective merely because it has occurred to appellate counsel that more questions might have been asked. “That attorneys disagree on trial strategy does not mean that the course chosen amounts to incompetency.”
Commonwealth v. Ramsey,
Appellant also contends his counsel was derelict in not introducing into evidence at trial certain allegedly exculpatory evidence in her possession. This “evidence” consisted of certain correspondence and investigation indicating that rapes committed by one Simpson in 1976 in the general vicinity of South Street were so similar to the instant crime as to suggest Simpson was the rapist herein and not appellant. However, the record is clear that trial counsel did not come into possession of this material until after appellant’s trial. Several hearings on counsel’s post-trial Brady 6 motions were held and relief was denied. Counsel cannot be deemed ineffective for failing to introduce material at trial about which she was not then aware. Should appellant or his counsel subsequently discover evidence suggesting appellant’s innocence, appropriate relief *219 may be sought under the Post Conviction Hearing Act, Act of January 25, 1966, P.L. 1580 (19 P.S. §§ 1180-1 et seq.).
Lastly, appellant posits the following issues, none of which were set forth in his post-trial motions. The claims are therefore waived.
Commonwealth v. Gravely,
1. Whether the identification of appellant by the victim was unnecessarily suggestive and, if so, whether the in-court identification was tainted thereby;
2. Whether the court’s charge on identification testimony was erroneous;
3. Whether the court’s charge on reasonable doubt was erroneous.
Judgment of sentence affirmed.

. The Bertillon system is a “method of anthropometry, used chiefly for the identification of criminals and other persons, consisting of the taking and recording of a system of numerous, minute, and uniform measurements of various parts of the human body, absolutely and in relation to each other, the facial, cranial, and other angles, and of any eccentricities or abnormalities noticed in the individual.” 10 C.J.S. p. 346; Black’s L.D. (4th ed.).
. The court instructed the jury that it was not to presume appellant had a police photograph prior to his arrest when he, in fact, did not. Trial counsel agreed with this caution. N.T. 501.
. As appellant is represented on this appeal by new counsel, the issue of trial counsel’s effectiveness is properly before us.
