D.C. police have released a video of a man they say followed a woman off a Metro train in Northeast Washington last week and sexually assaulted her at gunpoint.

The attack occurred about 11:15 p.m. on Sept. 6 near the Deanwood Metro station. The video shows the man getting off a train and following the victim through the station’s tunnel.

Police said the woman was assaulted in the 1300 block of 45th Place, NE, about two blocks from the station near the Anacostia Freeway.

The man is described as black, in his early to mid-20s, standing about 5 feet 7 inches and weighing 160 pounds. He was last seen wearing a white polo shirt with a dark horizontal strip across the middle, and khaki pants.

Anyone with information is urged to call D.C. police at 202-727-9099 or text 50411.
