After a month-long investigation, detectives determined that Nugra Ruiz tried to sexually assault a female juvenile victim
inside a Moonachie home. They also determined that he committed criminal sexual contact with the same girl between January 2025 and February of this year, in Little Falls.

Nugra Ruiz was arrested in Paramus and charged with second-degree sexual assault, two counts of third-degree endangering the welfare of a child, and three counts
of fourth-degree criminal sexual contact.

He was taken to the Bergen County Jail to await a first appearance in Bergen County Superior Court in Hackensack.
