A Bronx teacher’s aide was arrested Saturday evening and charged with sleeping with a 14-year-old student at her home, police said.

Maria Contreras, 29, a substitute paraprofessional at the Bronx Academy of Letters, is accused of bedding the boy several times at her apartment starting Nov. 11, police sources said.

The boy later told one of his parents, according to sources.

Contreras was charged with rape with a victim under 15, and engaging in a criminal sex act.
