Lawrence police are investigating a report that an unidentified man inappropriately showed his body Monday to two Lawrence girls along 15th Street.

The girls reported walking along 15th Street when they passed a red, four-door truck that was parked facing south at the intersection of 15th and Maple streets. The driver then allegedly pushed open the passenger door and exposed himself to the girls, police said.

The man then reportedly smiled at the girls, who are 12- and 13-years-old. The victims told the mother of the 13-year-old, and she reported the incident to police.

Police didn’t find the truck in the area and ask anyone with information to call (785) 843-TIPS, an anonymous tips hot line.
