LARGO, Fla. — A Pinellas County man is facing charges after his arrest Wednesday for standing at an open window and repeatedly masturbating as he watched students walk home from school, according to arrest documents.

The documents allege 30-year-old Gary Singer intentionally looked at the victims as he masturbated, and didn't stop until they screamed and ran away.

Singer told authorities he knew the exact times the students walk by and when they get off the bus, according to the documents.

He denied that he was masturbating. He told police he was "adjusting his hernia, while pulling his pants up," according to the documents.

Singer was arrested for lewd and lascivious exhibition with a $20,000 bond. Arrest records show he has been arrested multiple times for exposure of sexual organs.
