Police officers shot and killed a man in Gaithersburg, Md., on Friday night when he displayed a gun after a foot chase, according to Gaithersburg’s chief of police.

On Friday, the Gaithersburg Street Crimes Unit, composed of plainclothes officers, received information that a man was possibly armed in the area of 14 Fulks Corner Avenue, said Gaithersburg Police Chief Mark Sroka.

Four of the officers placed the man under surveillance, Sroka said. At about 5:50 p.m., the officers approached the man on foot and identified themselves as police officers, Sroka said. The man ran, and the officers chased him across six lanes of traffic on Route 355 to the Chelsea Park Apartments, Sroka said.

“When he reached that area, the suspect displayed a handgun,” Sroka said.

At least one officer “discharged their firearm, fatally striking the suspect,” who died at the scene, Sroka said. He said the investigation will determine exactly how many officers fired and how many rounds they fired.

The foot-chase lasted about a quarter of a mile, Sroka said.

Officers found a semiautomatic handgun, believed to be the suspect’s, at the shooting scene, Sroka said.

The area where officers first approached the man is near Gaithersburg’s police headquarters. There was no indication the man was there to harm any officers, said Officer Dan Lane, a Gaithersburg police spokesman.

The chief did not release the name of the decedent or the officers involved but said he expected to do so soon and possibly over the weekend.

At 10 p.m. Friday, a huddle of investigators could be seen examining the shooting scene.
