Police are looking for a man who they say grabbed and sexually assaulted a woman as she walked on Robie Street early Sunday morning.

The 25-year-old female was walking in the area of Shirley Street around 12:45 a.m. when police say a man came up from behind and grabbed her. He then allegedly reached up her skirt and “inappropriately touched her,” a police release states.

The woman screamed and the suspect fled the area.

Police describe him as a white male between 25 and 30, five-foot-10 and unshaven.
