CHICAGO -- A woman was sexually assaulted and robbed during a home invasion in the city's Bucktown neighborhood.

The break-in happened on the 2100 block of West Concord Place late Sunday night.

Police say a gunman broke into the woman's apartment after 11 p.m. through a back entrance.

A man got into an apartment, pulled out a gun, and forced a woman to take off her clothes.

He tied her up and fondled her, before he left with some electronics and her bicycle.

He has not been arrested.

Police have given a vague description of the suspect: African American man, 6 ft tall and about 175 lbs.

Police are looking at various surveillance cameras around the area for possible images of the suspect.
