Convicted after a jury-waived trial on three indictments charging him with crimes 1 related to his possession of a loaded handgun, the defendant argues on appeal that his motion to suppress the revolver and ammunition, which he jettisoned while fleeing from a Boston police officer, was improperly denied. After a hearing, a judge of the Supe *441 rior Court had issued written findings and concluded that the officer, Michael F. Devane, had developed a sufficiently ar-ticulable basis to justify a stop of the defendant once he began to run. We affirm.
The facts found by the motion judge, which we have embellished with undisputed details from the record, are as follows. 2 At approximately 9:00 p.m. on July 4, 1990, Officer Devane and his partner Officer Perkins were on patrol in the area of Columbia Road and Dudley Street in Boston. The officers’ interest was piqued by a man sitting atop an electrical box, who, upon their approach, began banging on the box by swinging a set of keys attached to a rope. Seeing nothing else unusual, the patrolmen moved on. A little over an hour later that evening the two officers responded to a breaking and entering committed at the same intersection. At the scene, Officer Devane learned that suspects had broken down the door of an abandoned building and then gained entry into an adjacent clothing shop through the dividing wall. Two individuals were apprehended and, in the process, a police officer was injured.
Ten days later, while on patrol in a marked cruiser around 8:45 p.m., the same two officers decided, with the earlier crime in mind, to question a group of young men who were standing near the site of the earlier break. As he approached the group, Officer Devane noticed the defendant appear from around a corner near the doorway of the abandoned building, which was now boarded up. The defendant, walking on the sidewalk about a foot from the building, came straight toward the officer. Although Officer Devane admitted that he was unable to discern if the door to the building was ajar, he attempted to ask the defendant a few questions. Then the character of his inquiry began to change. Without breaking *442 stride, the defendant bluntly shouted “Fuck you,” brushed by the group, and broke into a run. Officer Devane gave chase. 3 During the course of a short footrace, the defendant threw a gun aside, and was subsequently caught and arrested.
We start with the proposition that the Fourth Amendment to the United States Constitution does not require suppression of the evidence. In
California
v.
Hodari D.,
Whether art. 14 affords more expansive safeguards than those provided under the California v. Hodari D. formulation has not been addressed directly by a Massachusetts appellate court. Because we affirm the judge’s order on other grounds, we need not decide the question in this case.
In our view, the defendant’s cause is not advanced by
Commonwealth
v.
Thibeau, supra.
There are significant factual distinctions between the circumstances of the pursuit in the instant case and those described in
Thibeau.
In that case the show of authority sufficient to constitute a seizure (the chase by the police “with siren blaring”) began
before
the defendant engaged in any action that could be described as flight. The court stated that Thibeau “fled when pursued.”
Id.
at 763. In contrast, here the defendant’s decision to run away was not prompted by any inappropriate police action. Because we conclude that Officer Devane permissibly could have detained the defendant for the purpose of conducting a legitimate field inquiry, once the defendant began his flight, we do not have to reach the question whether, after
California
v.
Hodari D., supra,
art. 14 may provide more protection than the Federal Constitution with respect to “seizures” of individuals. See
Commonwealth
v.
Fraser,
The Supreme Judicial Court has recently revisited its decision in
Thibeau.
Writing for the court in
Commonwealth
v.
Laureano,
“There we held that the police pursuit, with siren blaring, of a bicyclist required some articulable facts leading to reasonable suspicion prior to the start of pursuit because in those circumstances, the stop (and seizure) began when the pursuit commenced. The claim of police ‘pursuit’ by the defendant, however, is not a talis-manic formula for converting all police investigation into a stop and seizure (emphasis supplied). ... In this case there was no evidence of pursuit in the sense that the term was used in Thibeau. The [plainclothes] detectives merely followed the defendant into a public rest room where they both had a right to be.”
The defendant does not dispute that his flight may be considered as a factor in evaluating the officer’s articulable suspicion, because “the defendant broke away from the police before they pursued him.”
Commonwealth
v.
Sanchez,
Although this is a close case, we think that Officer Devane’s pursuit of the defendant (and consequently his “stop” for our present purpose) was justified in the circumstances. The judge found that Devane asked the defendant
*445
“to stop for a minute” so that “he could check the doorway to see if there was any attempt at breaking and entering” because “the officer could not see the doorway from where he was standing.” Given the background of the earlier breaking and entering, it was not unreasonable — in fact it was good police work
5
— for Officer Devane to approach the group of men, who, from his perspective, may have been serving as lookouts for accomplices involved in further criminal activity. Cf.
Commonwealth
v.
Matthews,
Judgments affirmed.
Notes
The indictments were brought under G. L. c. 269, § 10(a) (carrying a firearm); G. L. c. 269, § 10(A) (possession of ammunition); and G. L. c. 266, § 60 (receiving stolen property).
The defendant does not quibble with the facts found by the motion judge, which are supported by the evidence.
Commonwealth
v.
Sanchez,
The motion judge found that the defendant’s flight preceded the officer’s pursuit, and the defendant has conceded as much.
Although Massachusetts has apparently adopted, under art. 14, the
pre-Hodari D.
test for determining when a seizure of an individual has occurred — that is, whether “a reasonable person would have believed that he was not free to leave[,]”
