CENTERVILLE A man was wounded by shrapnel from a toilet when his concealed weapon accidentally went off while he was using the bathroom, police said. It happened Tuesday at the Carl's Jr. restaurant at 385 N. 800 West. Police said the 26-year-old man had gone into the bathroom to use the toilet, armed with a .40-caliber Kahr P40 handgun. The man, who has a valid concealed weapon permit and was lawfully in possession of the gun, had it in a holster inside his pants. "While pulling his pants up the gun fell out of the holster, striking the tile floor," Centerville Police Lt. Paul Child said Wednesday. "When the gun hit the floor, it went off, and the bullet struck the toilet, shattering it and sending sharp pieces of porcelain flying." The man was hit by some porcelain shards, lacerating his arm. No one else was injured, but an employee of the restaurant in the next-door women's restroom heard the gunshot and panicked. "She was shaken, she was upset and was complaining of some chest pain," Child said. The man walked into the restaurant area, holding his wound and asked an employee to call 911. Police and paramedics responded to the call of shots fired inside the restaurant and ended up treating the man for the cuts to his arm. The woman also was treated at the scene.
