HACKENSACK — A 23-year-old Paramus man has been arrested for allegedly engaging in "inappropriate sexual activity" with a young girl two years ago.

Anthony Yachouh was taken into custody on Thursday, after an investigation by the Bergen County Prosecutor's Office and the Paramus Police Department, authorities said.

The state's Division of Child Protection and Permanency first learned of the alleged abuse against the girl, who is now 8 years old, according to Bergen County Prosecutor John L. Molinelli.

"The incident is alleged to have occurred about two years ago when the victim was 5 or 6 years old but only just reported," he said in a statement.

Yachouh, who is unemployed, is charged with sexual assault and endangering the welfare of a child.

He is being held at the Bergen County Jail in lieu of $100,000 bail, and has been ordered to have no contact with his alleged victim.
