A registered sex offender has been warned by cops to stop disrupting children in a Bernal Heights schoolyard.

Police were called to Paul Revere Elementary School at 555 Tompkins Ave. around 1:15 p.m. Wednesday on a report that a man was creating a disturbance. When cops arrived, the man was shirtless, according to Ingleside Station police.

A school counselor told cops the man had also come to the school on Tuesday and was “acting erratically and disrupting” the children, police said.

Cops discovered the man was a registered sex offender, then called the Police Department’s Sex Crimes Unit. They were told the man’s behavior did not violate the law, police said.

The man received a warning, police said.
