A 911 call about an alleged assault led Wichita police to a man suspected of trying to rob a convenience store.

KFDI-FM reports the call was made late Thursday by the girlfriend of the suspect, who received minor injuries in a fight with the store’s female clerk.

Police Lt. Doug Nolte says the 28-year-old man entered the Jump Start store around 11:30 p.m. and showed a gun. The 23-year-old woman behind the counter gave him cash, but grabbed the gun and hit him with it when he demanded money from the safe.

The clerk then dragged the robber outside and told him to leave. Officers arrested the man at his girlfriend’s home.

Police say the clerk thought the gun was a toy. She was also treated for minor injuries.
