Someone opened fire at a parole office on Tuesday, wounding at least one person, police say, and a suspect is on the run.

The shooting happened about 11 a.m. at a state Department of Corrections office in Detroit, Officer Leon Rahmaan said.

Rahmaan said the identity of the shooter, whether the shooter was in custody and other details were not immediately known.

But local FOX affiliate WJBK reported that two people were shot. A 27-year-old male is in critical condition, while a 33-year-old male is in serious condition at a Henry Ford Hospital.

WJBK reported that officers have established a perimeter in the Hamtramck neighborhood, where they have recovered the suspect's getaway vehicle — a green minivan — as well as an AK-47 assault rifle. A foot search is now underway.

Police believe the suspect is still armed, possibly with another AK-47 assault rifle.
