A second MBTA Transit Police officer was shot and slightly wounded in a gunfight with accused Boston Marathon bomber Tamerlan Tsarnaev, MBTA officials said on Wednesday.
The T did not release the officer’s identity, but said he was grazed in the buttocks during the gunfight early Friday in which MBTA officer Richard Donohue Jr. was severely wounded.
Donohue, 33, was wounded when he raced to help MIT and Cambridge police officers as they chased the Marathon bombing suspects to Dexter and Laurel streets in Watertown.
During the shoot-out, a bullet ripped through Donohue’s right thigh, hitting both branches of the femoral artery and the femoral vein, authorities said.
His friend and police academy classmate, Sean Collier, a Massachusetts Institute of Technology police officer, had been killed earlier, allegedly by Tamerlan Tsarnaev, 26, and his brother, Dzhokhar Tsarnaev, 19.
At a community public safety meeting in Dorchester on Wednesday, MBTA Transit Police Lieutenant Bill Fleming said Donohue “basically died’’ until emergency workers revived him.
Donohue was listed in serious but stable condition Wednesday evening at Mount Auburn Hospital.
Fleming said another officer was grazed in the buttocks in the shoot-out.
“He didn’t report it,’’ Fleming said at the meeting. “He was embarrassed.”
“The officer was treated at the scene for a minor injury,’’ said Joseph Pesaturo, spokesman for the Massachusetts Bay Transportation Authority. “He is back on duty.”
