PHILADELPHIA (CBS) -- Philadelphia police hope new surveillance images will help them find the suspect in an officer-involved shooting outside a nightclub. Police say an officer was working a nightclub detail on Lancaster Avenue in Philadelphia's Powelton neighborhood.

They say security guards got into a fight with a man in front of the club.

The man ran off, then returned, pulled out a gun and fired at the officer and a security guard, according to police.

Investigators say both returned fire.

The suspect got into a car and drove off. There were no major injuries.

If you recognize the suspect, call Philadelphia police.
