Shocking security camera footage shows the moment an off-duty cop opens fire on two armed robbers on a bus in Mexico, before being fatally wounded when they return fire.
The incident occurred the evening of June 24, in Valle de Chalco Solidaridad, a municipality in the State of Mexico.
The bus' surveillance camera shows one of the two robbers ordering demanding passengers on board give up their valuable belongings.
The muggers tried to escape from the bus, but were caught by the passengers outside and beaten to death, local media reported.
Two passengers were also wounded.
