Chopper 3 was over the scene, showing a flurry of officers on the ground.

Police radio reveals the heart-pounding moments that followed when an officer was shot after he was attacked by a man just after 3 p.m. on the 5700 block of Overbrook Avenue near Saint Joseph’s University.

“More units, we need some more units. Send help, my partner’s down,” a voice said over the radio.

Police say the suspect had a hammer and pickaxe and walked toward police. Officers used a taser and the suspect fell to the ground before getting up and charging at police, according to authorities.

A scuffle then ensued.

That’s when an officer opened fire and hit the suspect, and also hit the officer in the leg. The suspect has died.

The officer was rushed to Penn Presbyterian Medical Center where a source says he is listed in stable condition.

“During this attack, the male officer who had discharged his officer’s, is struck in the head with one of the weapons, knocking him to the ground,” Philadelphia Police Commissioner Danielle Outlaw said. “While the officer was on the ground, the offender then mounted the officer, sitting on top of him, and struck him repeatedly with one or both of the weapons. At this point, we know that officers drew their service weapons and fired multiple shots at the male, striking him and ending the attack.”

The Philadelphia mayor, police commissioner and the president of the city’s police union are all at the medical center.

The incident happened in the area of Samuel Gompers School, behind St. Joe’s University.

Students tell CBS3 they heard several shots.

“It was five, six-ish, maybe, in a cluster,” student CJ Donofry said.

No St. Joe’s students were injured, but an alert was sent to all members of the SJU community.

“And it just kind of scared me because I wasn’t expecting it walking to class,” student Keeley McGuigan said.
