LYNDHURST — An educator lost his job at Lyndhurst High School after exchanging sexually explicit messages with underage girls, prosecutors charged this week.

Jonathan Jasinski, 26, resigned from his position at the high school before his arrest on Thursday on charges of second-degree endangering the welfare of a child and third-degree possession of child pornography.

Jasinski, a township resident, had been a substitute teacher, an in-school suspension officer and an assistant coach of the hockey and baseball teams.

The Bergen County Prosecutor's Office said Jasinski chatted with the underage girls online and traded the pornographic pictures with them.

Jasinski was released from jail on Friday and ordered not to contact any underage person without supervision, not to communicate with anyone online and to surrender his passport.
