D.C. police on Saturday released grainy video footage of a man they say is a “person of interest” in a sexual assault earlier this month.

The footage shows a man in a baggy, hooded sweatshirt, though it is difficult to make out any distinguishing characteristics. Police described him in a news release as black man in his 20s, about 5 feet, 7 inches tall, with a slim build, short black hair and a goatee. The man was last seen wearing a black skull cap, tan jacket over a gray hooded sweatshirt, white washed blue jeans, and black and white Nike Jordan 3 shoes, police said. He might go by the name “Moses,” police said.

The assault occurred about 11 a.m. March 1 while a woman was walking in the 700 block of Barnes Street, NE, police have said. Police have said a man approached the woman from behind, pulled out a handgun and sexually assaulted her next to a residence. They have said the woman did not know her attacker.

Anyone with information is asked to call D.C. police at 202-727-9099.
