Manatee County sheriff's deputies said Charles Ross, 18, of Bradenton, and a friend went to the Royal Palm Theater Sunday night and Ross began giving wedgies to strangers while his friend took video footage, the Bradenton Herald reported Tuesday.
Deputies said most of the alleged victims were too embarrassed to press charges, but one said charges would be filed.
Investigators said Ross is known by local law enforcement for pranks he pulls for his YouTube videos.
Ross and his friend were ejected from the theater and told they would be arrested if they returned. The camera was seized as evidence.
