Police say vandals who broke into Anderson High School’s historic Wigwam complex smashed a window and set off several fire extinguishers inside the building. Authorities were alerted to Saturday’s break-in when the discharge of the extinguishers set off alarms. Police said vandals caused some damage inside the building, but didn’t hurt the 9,000-seat gymnasium. The Wigwam was built in 1962 and is the world’s second-largest high school basketball venue. It was closed in 2011 as a cost-cutting measure.
