At about 5:30 p.m., a man wearing no clothes went into a locker room at South San Francisco High School and exposed himself to five girls who were changing after cheerleading practice, police Sgt. Bruce McPhillips said.
Witnesses told police the suspect made eye contact with the girls and then left without saying anything, McPhillips said. He did not touch anyone, and no one was injured.
As of this morning, the suspect had not been identified.
He was described as a white man around 40 years old and 5 feet 10 inches tall with an average build. He is balding with short brown hair, and has a potbelly, police said.
