(AP) – University of Kansas police are investigating several acts of vandalism at campus buildings this month.

The vandalism began July 12 when someone caused $5,000 in damage to a bathroom at Wescoe Hall and benches on the building’s ground floor.

Damage was later reported at Blake Hall, Fraser Hall, Malott Hall and Stauffer-Flint Hall.  The total damage was estimated at $9,000.

All the buildings were unlocked because people were working inside.  It’s not clear if all the vandalism incidents are related.
