Authorities are looking for a suspect who shot and wounded a man in North Philly Saturday — while a cop watched the incident unfold.

A Philadelphia police officer parked a vehicle on the 2600 block of West Cumberland Street in Strawberry Mansion around 10:15 p.m., according to   The Philadelphia Inquirer. About two minutes later, the officer, whose identity wasn't disclosed by authorities, heard a gunshot. 

Looking to his left, the officer saw a man in a burgundy jacket fire several more shots at another man. The gunman then tucked the weapon in his pants and fled the scene on foot, police said.

Officers later found a burgundy jacket and a silver revolver in an alleyway near the scene of the shooting. The gunman remains on the loose and has not been identified, according to the Inky.

The victim approached the witnessing officer and told him he had been shot in the shoulder. He was transported to Temple University Hospital.

The Inquirer reported that a spokesman for the PPD didn't know whether the witnessing officer was in a marked or unmarked police vehicle.

It's also unclear whether the officer was on duty or in uniform at the time of the shooting.
