The shooting happened near G and Madison Streets In Kensington, shortly after 11 a.m.
Chopper 3 was over the scene where a massive police response could be seen.
The officer was shot in the leg and taken to Temple Hospital. The officer is in stable condition.
Philadelphia Police Commissioner Richard Ross identified the officer as 31-year-old Paul Sulock who is a 10-year veteran of the force. He is also a father of four.
Ross says Sulock and his partner interrupted a shooting that was in progress between two men.
“We are very fortunate right now given those circumstances. We know they interrupted what was probably a shooting,” said Ross.
Ross added that Sulock chased one of the suspects after being shot and apprehended him.
Sulock is expected to be OK and is in “good spirits,” said Ross. He is expected to be released from the hospital on Thursday.
“We know a police officer was shot doing his job, doing it bravely, and then subsequently chasing down the person that shot him which is no doubt, valor to the highest degree and we’re glad he is OK,” said Ross.
The officers did open fire on the suspects, but the suspects were not struck by any gunfire.
Detectives are viewing surveillance video to fill in some of the gaps of the investigation.
