Police say a Philadelphia pastor's wife pulled out a gun and shot an armed man who was trying to rob her and her family.

Pastor Robert Cook, his wife and 12-year-old son were returning home when they were approached by a man armed with a rifle Thursday night.

Police say a struggle began when the man demanded the pastor's wallet and hit the pastor on the head with the butt of the rifle. Police say that's when the pastor's wife pulled out her licensed gun and shot the man in the leg.

Cook tells WPVI-TV (http://6abc.cm/2d50UKA ) "everything was like lightning for a minute." He says he told his wife to shoot the suspect and she did.

The suspect was apprehended and treated for his wound.

The shooting is under investigation.
