Cowardly thug robs 85 yr old woman from behind in elevator

CCTV:Police released video on Monday capturing a cruel punk's attack on an 85-year-old Brooklyn woman ? and she's not his only victim. The surveillance video shows the robber following Lilian France into the elevator of a Crown Heights building, stalking her into a hallway and then choking her from behind. France waved her arms, desperately trying to throw off her attacker. She was left panting on the floor as he ran off with $900 ? and her cane, the video shows. Police believe the cowardly thug has gone after nearly a dozen seniors in Crown Heights, Kensington and Flatbush during the last few months. The robber ? described as a man in his 20's or 30's sporting a "nice watch, baseball cap and white sneakers" ? likes to follow his prey into their apartment lobbies to share an elevator ride, said police. Then, "he approaches them from behind," said NYPD spokesman, Assistant Chief Michael Collins. "Either knocks them over or puts them in chokehold."
