ST. LOUIS • A man pumping gas Wednesday morning turned the tables on a would-be robber who may be tied to a string of other crimes.

Police say the man was at the Phillips 66 station at 4500 North Broadway about 7 a.m. when a dark-colored car pulled up. A man jumped out of the passenger seat and tried to rob the victim.

But the victim had his own gun and pulled it on the would-be robber, shooting him in the buttocks.

The wounded robber fled to the 6100 block of North Broadway and got medical help, said Leah Freeman, a police department spokeswoman.

Freeman said the suspect, a man in his 20s, was stable. His accomplice, the driver, got away.

The victim was not hurt, police say. He had a permit to carry a concealed weapon.

Police say the robbers in that botched crime are suspected in a holdup an hour earlier at Hollywood Casino in Maryland Heights and two other robberies.

In the robbery at Hollywood Casino about 6 a.m. Wednesday, two men drove into the parking garage in a dark-colored car. One of them approached a man who was leaving the casino and tried to rob him at gunpoint in a parking garage, police say. But the victim in that case had just lost big at the casino.
