Long Beach city police are looking for the gunman who shot another man outside police headquarters early Sunday.

Sgt. Eric Cregeen said the victim, a 22-year-old man, was taken to an area hospital, where he faced surgery for bullet wounds to the lower back and behind the right knee and was listed in critical condition.

A dispatcher at police headquarters on West Chester Street thought he heard gunshots at about 2:30 a.m. and called a unit to patrol the area, Cregeen said.

Moments later, the victim walked into headquarters and reported he had been shot.

Cregeen also said police found a bullet hole in the glass of an entrance door to headquarters.
