District police are looking for a man who they believe sexually assaulted a woman and tried to attack two others who were walking along a footbridge last week outside the Minnesota Avenue Metro station in Northeast Washington.

Authorities released a video that shows the man leaving the Metro station. D.C. Police Chief Cathy L. Lanier, at a community crime meeting Monday night in Deanwood, urged residents to help identify a suspect.

The first attack occurred about 11 a.m. on March 1. Police said a man accosted the woman on the footbridge and forced her several blocks away to an address in the 700 block of Barnes Street NE., behind the Metro station. There, police said, he sexually assaulted her.

On Friday, police said, a man approached a woman from behind as she left the station about 7:10 a.m. “The suspect told her to follow him and said something to the effect that he would shoot her if she did not follow,” police said in a statement. The woman kept walking and the man gave up after following her for a bit, police said.

Twenty minutes later at the same station, police said a man came up behind another woman. “The suspect told her to ‘come here,’ ” police said in a statement. The woman didn’t respond, and the man repeated it. The woman then started talking to a bystander, pretending to know him in hopes of thwarting an attack. Police said the man who had approached her followed her but then gave up.

Police describe the man as black and in his 20s, standing about 5 feet 7 inches tall with a thin build, short black hair and a goatee. He was last seen wearing a black skull cap, tan jacket over a gray hooded sweatshirt with a single front pocket, whitewashed bluejeans and black-and-white Nike Jordan 3 shoes. Police said he may go by the name Moses.

Anyone with information is urged to call D.C. police at 202-727-9099 or text the tip line at 50411. Police are offering a $1,000 reward for information leading to an arrest and a conviction.
