The woman told police she was in the 3800 block of North Wilton Avenue around 10:45 p.m. when two men and two women physically and sexually assaulted her.

Chicago police have determined that a previously reported sexual assault in Lake View did not occur. A 26-year-old woman had initially claimed she was attacked in an alley late Sunday night by two men, who then fled with two women. After investigating, authorities deemed the report unfounded by midday Monday.
