Northwestern University police say a man who claimed to be seeking petition signatures for a charity knocked on the door of a residence in the 800 block of Simpson Street about 7:30 p.m. Saturday.
When a resident opened the door and stepped out to speak with the solicitor, police say, the man asked a series of personal questions and touched and then hugged and fondled the resident before leaving.
A police crime alert provided no further description of the suspect, but asked anyone with information about the incident to call NU police at 847-491-3456 or Evanston police at 847-866-5000.
