A physical education teacher at Dickinson High School in Jersey City is accused of sexually assaulting a 17-year-old student, authorities said.

Francisco “Mike” Realpe, 43, was arrested Monday night at his home in Hoboken and charged with aggravated sexual assault, criminal sexual contact, and endangering the welfare of a child.

Hudson County Prosecutor Esther Suarez said the state Division of Child Protection and Permanency first reported the alleged sexual assault to the HCPO on Jan. 31.

Realpe has been at Dickinson High School since 2005, according to his LinkedIn page. He earned an annual salary of $84,019 as of March 2019, payroll records indicate.

Norma Fernandez, a spokeswoman for the Jersey City Board of Education, said Realpe was removed from the school once the allegations surfaced, but he remains employed pending the outcome of the investigation.

Authorities did not specify where the alleged sex assault took place.

Suarez said he was transported to Hudson County jail in Kearny, where he awaits his first court appearance on the charges.
