The Monmouth County prosecutor says a former teacher at an elementary school in Long Branch has been charged with sexually assaulting multiple elementary school children.

Gustavo Barrientos, 53, of Tinton Falls, was arrested last month after allegedly showing a 10-year-old female student pornography, and sexually assaulting her on multiple occasions. The incident happened during his time as an elementary school teacher in the Long Branch School District. Police did not reveal which school.

It's unknown exactly how many other children Barrientos is accused of assaulting. Police did not reveal the children's ages or locations.

Authorities say he also previously worked at Red Bank Charter School.

Anyone who has information about Barrientos' actions should contact Detective Sgt. Shawn Murphy, of the Monmouth County Prosecutor's Office Special Victim's Bureau at 800-533-7443 or Detective Todd Coleman, of the Long Branch Police Department at 732-222-1000.

Barrientos is currently being held in the Monmouth County Jail.
