A man clad in only Spider-Man underwear wasn’t fighting crime on the streets of Cincinnati. According to police, the Spidey undies suspect was doing the opposite – vandalizing an area high school.

Thomas Williams, 23, of Kenwood, Ohio, was charged with vandalism and breaking and entering for allegedly spraying fire extinguishers inside Archbishop Moeller High School in Cincinnati, according to authorities, the Cincinnati Enquirer reported.

Williams allegedly broke a bunch of windows at Moeller High by throwing rocks.  The Spider-Man underwear-wearing suspect gained access to the Cincinnati high school through a window, the paper reported.

When Williams was arrested on vandalism and other charges, he was found to be wearing Spider-Man underwear, according to the Enquirer.

Police are unsure what allegedly motivated Williams to commit the crime or to wear Spider-Man underwear.
