Watch: Philadelphia Police Officers Involved In Standoff Shooting

Some officers had to escape through the windows after gunman opened fire

Officers returned fire at the shooter, Philadelphia Police Commissioner Richard Ross said at a press conference Wednesday.

Some of the officers who were responding to the incident had to escape through windows and doors, Ross said.

One officer had a gunshot wound grazing his head, but all six officers who were shot have non-life-threatening injuries and “everybody is going to be okay,” he said.
