Ed. guard rape bust

A city school-safety agent was arrested yesterday morning for allegedly raping his ex-girlfriend in a vicious assault that he recorded on his cellphone, police said.

Tommy Johnson, 28, attacked his fellow school-safety agent, whom he’s allegedly stalked and menaced, at her Brooklyn apartment Saturday, sources said.

“I know you’re screwing around! Who is he? You’re going to make me kill somebody,” Johnson allegedly snarled before pulling a handgun, sources said.

Johnson allegedly punched and bit the woman on her face before forcing her into a bedroom and raping her, using his phone to record the crime, sources said.

After the attack, the victim, 35, went to work and then called the cops.

“These days anyone can make allegations. I’m hoping that they’re just that,” said a man who identified himself as Johnson’s brother at the family’s Ridgewood, Queens, home.

Johnson, who was assigned to a Queens school, was suspended from his $34,000-a-year job, police said.
