The Cincinnati Enquirer reports that it happened early Sunday when a suspect used rocks to break several windows at Moeller High School, crawled in one of the windows and sprayed fire extinguishers around the building.
Hamilton County sheriff's deputies say 23-year-old Thomas Williams was wearing Spider-Man underwear when he was arrested. The 6-foot-5, 295-pound Kenwood man was charged with felony vandalism and breaking and entering.
Police reports gave no explanation for Williams' attire.
Williams was still in jail Monday morning. Online records didn't indicate if he had an attorney.
