A person has been taken into custody in Revere after a Massachusetts state trooper's gun was fired during a traffic stop, police said.
No one is believed to have been hit by gunfire, and the troopers conducting the stop were not shot at, police said.
The troopers, one of them a rookie, had pulled an Audi over on Shirley Avenue, according to police. The 21-year-old driver was wanted in connection with a different traffic stop from several weeks before.
When the troopers approached the vehicle and ordered the driver to get out, he started to drive off, injuring one of the officers in the leg. One or both of the troopers fired their weapon, police said. Both troopers were taken to the hospital.
The driver wasn't hit and the Audi fled the scene, but he was arrested soon afterward by Revere police, who caught him after a chase on foot, according to state police. The driver, who remains in custody, was identified as Juan Pineda, of Lynn.
It wasn't immediately clear if Pineda had an attorney who could speak to the charge. He was set to be arraigned on charges including assault and battery on Thursday in Chelsea District Court, police said.
The incident remains under investigation.
Witnesses described a scary scene. One said he heard state police yelling, then two gun shots.
