Two people were wounded in an early-morning shootout at a Birmingham gas station.

The shooting appeared to stem from a robbery-gone-bad, and one of those wounded was one of the potential robbers, police said.

The gunfire erupted about 2 a.m. at the Shell gas station on Arkadelphia Road. Birmingham police spokesman Lt. Sean Edwards said a man and at least one woman had left a club and stopped at the service station for gas.

Another vehicle with three black males inside pulled up and words were exchanged. That's when the shooting started. The would-be robber was shot in the head, but is expected to survive. He was driven by private vehicle to the hospital.

A woman in the other vehicle was struck in the leg or buttocks area while sitting in the vehicle. That vehicle drove off, and police and paramedics were dispatched to a separate location. She also was taken to a local hospital but is expected to survive.

Edwards said investigators believe the suspects possibly followed the victims from the club with the intention of robbing them. The investigation is ongoing, but police aren't getting cooperation from any of those involved.
