D.C. police released photos of a man they want to talk with, after a woman was sexually assaulted Tuesday morning inside a business in the Shaw neighborhood of Northwest.

An unknown man walked into the woman’s workplace in the 1700 block of 7th Street NW about 9 a.m. Tuesday and then sexually assaulted her, officials said.

Investigators are trying to identify and speak with a man they describe as a black male in his early 20s, with a medium complexion, a skinny build, and short hair. He’s also said to be between five-foot-six and five-foot-ten.

The man was last seen wearing a gray shirt, black Helly Hansen pants, gray and green shoes, and a gray baseball cap. Police said he also has a tattoo on his right forearm with unknown letters and that he carried a blue, satchel-type backpack.

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