Police shot a gun-wielding robbery suspect in Brooklyn last night, at Howard Ave. and Marion St. According to 1010WINS, "Police say officers were canvassing the neighborhood after a report that two men -- one armed with a handgun -- had just tried to rob a 15-year-old...the officers spotted a man fitting the description and armed with a Glock 10 millimeter handgun." A police source tells the Daily News that cops told the suspect to drop his gun but the suspect "turned with the gun, and the cop shot him." Another witness said, "The cops started chasing him down the block. The cop was shouting, 'Stop or I'm going to shoot!' He tripped and fell. He was getting up. The cop shot him." The suspected robber is in critical condition at Kings County Hospital while the other suspect is at large.
