A high school teacher and volleyball coach, who appears to currently be employed in Union County, was arrested and charged by Morris County Prosecutor Frederic Knapp with aggravated sexual assault against two female students over a four-year span.

Knapp said Carlos A. Franco-Leon, 42, of Rockaway committed sexual acts with the teens, while he was both a teacher and coach at Morris Catholic High School in Denville between 2015 and 2019.

Franco-Leon's employment with the school ended in 2018, according to Knapp.

NJ.com first reported Franco-Leon currently is a teacher at Roselle Catholic High School in Roselle.

As of Sunday early afternoon, the school's website faculty directory  had a Carlos Franco listed as both a STEM instructor and varsity girls' volleyball coach.

A Carlos Franco Linkedin account page also lists work experience at both private high schools, as well as Immaculate Conception High School, another catholic high school in Montclair.

Newark Archdiocese spokeswoman Maria Margiotta in an email late Sunday night told New Jersey 101.5 Franco-Leon was suspended by the school and the archdiocese and was alerting staff and parents about the allegations.

"This is certainly of immense concern. The safety of our students and our faithful is of paramount importance, and providing a safe school environment for the students placed in our care remains a priority," Margiotta said.

Franco-Leon was charged with 6 counts of first degree aggravated sexual assault, 2 counts of second degree sexual assault and 2 counts of second degree endangering the welfare of a child, according to prosecutors.

He was being held at Morris County jail, pending a court appearance.

Messages for Morris Catholic and the Paterson Diocese were not immediately returned Sunday afternoon.
