Janitor faces dirty sex rap

A JANITOR at a Brooklyn elementary school was arrested for molesting several women there, including a teacher he caught alone in a classroom, police sources said.

Kasim Khan, 32, who works at Public School 222 in Marine Park, is accused of gyrating and rubbing his genitals on a 46-year-old teacher’s buttocks Tuesday inside the Quentin Road school, sources said. He faces forcible touching, sex abuse and harassment charges, and cops are looking into allegations involving at least four more staffers, sources said.

Khan is suspended without pay and is not allowed in any school building, Education Department spokesman Douglas Cohen said.

Several of the women complained about Khan to his supervisor, but their concerns were not immediately relayed to the school’s principal, police sources said. His boss has been reassigned pending the outcome of an investigation, school sources said.
