A 28-year-old Philadelphia police officer responding to a reported carjacking was grazed in the head by a bullet and a second officer was injured Monday night in North Philadelphia, police said.

The shooting happened around 8:10 p.m. on the 2200 block of North Reese Street, police said. The male officer, who was described as alert, was taken to Temple University Hospital.

A second male officer suffered a minor injury to his head, but it was described as not being caused by gunfire.

The police department posted a statement on Twitter saying the officer with graze wound was in stable condition.

“Thanks to everyone for their kind words and support as our brave officer … recovers from his injuries,” the department said, adding that the officer is a four-year member of the force.

The shooter was described as among a group of five or six males who ran north on Reese and was still at large.

It was not immediately clear what led to the gunfire. But the officers said they were shot at and took cover and were not able to return fire, police said.
