A 29-year-old Bronx teaching assistant was charged over the weekend with raping a young boy, police said.

The woman, Maria Contreras, allegedly raped the boy at the Bronx Academy of Letters, where she worked as a substitute paraprofessional, authorities said.

Contreras is accused of raping the 14-year-old boy on several different occasions from November 10 through January 31, according to the criminal complaint.

Contreras was held in lieu of $10,000 cash bail at her arraignment in Bronx Criminal Court last night. Her attorney did not immediately respond to a request for comment.

She was charged with several offenses, including six counts of second-degree rape of a victim under 15 years old, and two counts of second-degree criminal sex act with a child under 15.

"These allegations are incredibly disturbing," Department of Education spokeswoman Devora Kaye said in an email. “Ms. Contreras has been removed from her position and will no longer be employed by the DOE. We are working with NYPD on their investigation.”

Contreras' next court appearance is scheduled for Friday.
