The Lawrence Police Department is investigating four sex crimes in different areas of the city involving women who report they were illegally touched, the agency announced Tuesday.

A 19-year-old Lawrence woman said she was touched by a man Oct. 1 while trying on clothing at a downtown Lawrence clothing store. The victim said the man illegally touched her when she came out of a dressing room to look at clothes in a mirror, a police report said.

A 24-year-old Lawrence woman told police that a 21-year-old male acquaintance touched her sometime before 5 a.m. on Oct. 4 at a friend’s apartment north of Sixth Street, the police report said. Police said they forwarded this sexual battery case to the Douglas County District Attorney’s Office for review.

A 22-year-old Lawrence woman reported she was illegally touched by a 28-year-old male acquaintance about 10:30 p.m. Oct. 6 at a west Lawrence home. This case was also forwarded to the district attorney’s office for review.

Investigators said they’re also looking into a report that a 19-year-old Manhattan woman was illegally touched by a 21-year-old male acquaintance between Nov. 30, 2007, and March 1, 2008, after a party in south central Lawrence. The woman reported the incident to Lawrence police Oct. 5.
