The defendant at a jury trial was convicted of rape, unarmed robbery, and kidnapping. He appeals under G. L. c. 278, §§ 33A-33G. We summarize the events as they appear from the evidence.
On Saturday, June 23, 1973, at about 3:00 p.m., the victim, a young woman, was returning to her apartment on Park Drive in Boston from a shopping trip. As she approached the door to her building, the defendant grabbed her from behind and went with her into the vestibule of the building. He struck her and forced her to give him the money she had — about $30. He then forced her upstairs *483 to her apartment. Upon entering the apartment the defendant dragged the victim into the kitchen, picked up a kitchen knife, and then dragged her into the bedroom. We omit a description of the brutal details as the defendant terrorized and raped the victim. At one point the victim tried to escape; the defendant caught her as she reached the door, dragged her back to the bed, and struck her repeatedly. Her face was swollen. The defendant then ordered the victim to dress and come with him. He told her, “I’ve got a gun and if you try to escape I will shoot you or anyone else that tries to help you.” They went down by the cellar and out the back door.
The defendant led her down the Fenway and thence to a small Spanish restaurant on Tremont Street in an area unfamiliar to her. They stayed about fifteen minutes while the defendant had something to eat; the victim testified that she did not attempt to ask for help at that time because she believed that none of the restaurant employees understood English.
The defendant and the victim then boarded a bus. The victim whispered to the driver for help, but the driver made no move to come to her aid. The defendant and the victim got off at the next stop. Thereafter the defendant led the victim to a secluded area, demanded that she undress again, and forced her to perform an unnatural act, threatening to kill her.
The defendant and the victim then left the secluded area. As they passed by a fire station (it was now about 9:30 p.m.), the victim broke away from the defendant, ran into the station, and grabbed one of the firefighters, screaming for help. The defendant came into the fire station and said, “I want my woman.” When a firefighter suggested that they summon a police officer, the defendant fled.
A medical examination of the victim disclosed the presence of sperm in the vagina, lacerations of the vaginal and hymenal area, and a fracture of the orbital floor beneath the right eye.
At police headquarters the following day the victim looked through a number of boxes containing perhaps sev *484 eral hundred photographs kept in the identification section at the headquarters of the Boston Police Department; she made no identification. On Monday, June 25, she was shown a group of eleven photographs, from which she chose the defendant’s photograph. The proprietor of the Spanish restaurant and four firefighters subsequently chose the defendant’s photograph from the same group. At trial, all six persons identified the defendant.
We treat the assignments of error substantially in the order they are argued in the defendant’s brief.
1. Assignments 1, 2, and 3 attack the denial (or partial denial) of various discovery motions.
(a) The defendant’s motion to produce all photographs shown “to the victim and/or witnesses” was allowed only as to the group of eleven photographs shown to the victim on Monday, June 25, and later shown to the five other witnesses. The trial judge said: “I don’t want him [the prosecuting attorney] to be held to bringing in five hundred photographs shown at headquarters, but I do want the cluster of photographs which were shown to her which ultimately resulted in the alleged identification, shown to defense counsel.” The defendant argues, as he did at the hearing on the motion, that he was entitled to know whether the defendant’s picture was among those which the victim looked at as she originally went through the files without making an identification. However, that did not require the physical production of all the photographs she had examined. Although the Supreme Judicial Court has held that the police are not required to make a record of the preliminary perusal of identification files by a victim (see
Commonwealth
v.
Gibson,
(b) The motion requesting generally all statements, written or oral, made by the defendant
3
was allowed only as to written statements and oral statements reduced to writing. There was no abuse of discretion.
Commonwealth
v.
Colella,
(c) The general motion for exculpatory evidence was properly denied for the reasons set forth in
Commonwealth
v.
Preston,
2. Assignments 4 and 13 are concerned with the judge’s order to sequester witnesses.
(a) It was proper to exempt from the sequestration order Detective Farrell, a prospective Commonwealth witness, the investigating officer in the case, if “the prospective witness, as the judge impliedly found, [wa]s essential to *486 the management of the case.” Commonwealth v. Therrien, 359 Mass. 500, 508 (1971) . 4
(b) During the trial two Commonwealth witnesses testified that they had briefly discussed the case outside the courtroom with other witnesses. However, the trial judge determined that neither witness had spoken with any witness who had already testified, and this made pointless the defendant’s motion for a mistrial. The trial judge, in any event, has broad discretion in such matters; and this discretion was obviously not abused here.
Commonwealth
v.
Parry,
3. Assignments 6, 10, and 15 concern references by the prosecuting attorney and two witnesses arguably suggesting the defendant’s involvement in prior criminal activity.
(a) The victim testified that, as she and the defendant left her apartment, the defendant first referred to a radio station that “does the dedications to the prisoners” and then stated, “I just got out of Concord, you know.” The testimony was relevant, particularly to the kidnapping charge.
Commonwealth
v.
Chalifoux,
(b) The defendant moved for a mistrial after Detective Farrell testified that he had arrested the defendant at what he described as a “halfway house.” The judge promptly and forcefully instructed the jury to disregard the reference. There was no error in denying the motion.
Commonwealth
v.
Gibson,
4. Assignment 11. There was no abuse of discretion in permitting leading questions to be put to a Spanish-speaking witness for the Commonwealth who testified through an interpreter. See
Commonwealth
v.
Fiore,
5. Assignment 12. Testimony by the firefighter to whom the victim ran concerning the victim’s statements about what had happened to her was obviously admissible as evidence of fresh complaint. See
Commonwealth
v.
Hanger,
6. Assignment 16. Dining the cross-examination of Detective Farrell, testimony was elicited concerning the identity and whereabouts of the driver of the bus which the defendant and the victim had boarded.
5
At a bench conference the judge criticized defense counsel for creating the impression that the bus driver, though known to the prosecution, had not been produced by the Commonwealth because he might contradict the victim’s story. The judge requested that counsel for the defendant and the prosecuting attorney each make a brief statement to the jury as to the information concerning the bus driver which had been divulged before trial. Counsel for the defendant excepted “to being ordered to make this stipulation.” Both attorneys
*488
then made brief statements. There was no error. While the procedure invoked here may have been uncommon, it cannot be said that it in any way constituted an abuse of the discretionary power of a judge to regulate the course and conduct of a trial. It is the duty of the trial judge to guard against improper conduct and argument of counsel, and he has considerable latitude in his choice of methods to insure that end. See
Commonwealth
v.
O’Connell,
7. Assignments 17, 18, and 23 concern references by the prosecuting attorney in his cross-examination and by the trial judge in his charge to a probable cause hearing held in a Municipal Court.
(a) During cross-examination of the defendant’s mother, the prosecuting attorney asked the witness if she had testified at the probable cause hearing that the defendant had been in her house during the afternoon of June 23. The defendant objected and excepted. The witness responded, “I think I did.” Nothing further was elicited on this point. The defendant’s subsequent motion for a mistrial was denied, and the defendant excepted. The defendant relies on
Commonwealth
v.
Morrison,
(b) The defendant excepted to the judge’s charge explaining the nature of a probable cause hearing. There is nothing in the explanation (which was entirely relevant) from which the jury could have inferred that the defendant did not offer a defense in the Municipal Court. There was no error.
*489
9. We do not consider the remaining assignments of error. Some of them concern matters as to which there was no exception or other indication of dissatisfaction by trial counsel. See
Commonwealth
v.
Stone,
Judgments affirmed.
Notes
In that case it was established that the victim had recognized the defendant’s picture in the identification files, but the defense asked for all the other pictures viewed by the victim of which a record had not been made.
But see Superior Court Rule 101D, adopted April 30, 1971 (now Rule 63 of the Superior Court [1974]), imposing such a requirement.
At the hearing on the motion counsel for the defendant expressly waived the request with respect to statements made to the victim.
The trial judge offered to grant the defense a similar right.
The bus driver did not testify. It is clear from the record that before trial the Commonwealth had provided the defendant with the name of the driver, together with an address at which it was believed he could be located. The efforts of both sides to find the driver were unsuccessful.
