PHILADELPHIA (KTRK) -- Philadelphia police say one suspect remains at large after an off-duty detective shot and killed a gunman during a pizza store robbery.
Police officials say the detective was picking up food late Thursday when two men entered the store and put a gun to his head.
They say the pair forced him to the floor and took $20 from him before the detective identified himself and pulled his weapon.
Chief Inspector Scott Small says one suspect fired two shots from point-blank range before the detective returned fire.
Police say the pair then fled Rising Sun Pizza before the wounded 33-year-old suspect collapsed and died.
His name has not yet been released. Police have recovered his weapon. WPVI-TV in Philadelphia reports that one of the suspects was carrying a revolver loaded with blanks.
Authorities say the detective, pizza shop owner and an employee were unharmed.
