TINLEY PARK, Ill. (CBS) — Police are investigating after drawings of swastikas, the Star of David and various ethnic slurs were found on several driveways in Tinley Park.

The drawings were found May 2. They were done in chalk, leading police to believe they were done by children or teenagers and were connected to Osama bin Laden’s death, police said.

Similar drawings were found in a driveway of one house on Nielsen Drive on April 29, before the mission that killed bin Laden had taken place, police said.

The affected houses were the 8000 block of Nielsen Drive, Emily Court and Iroquois Trail, police said.
