DENVILLE — A routine motor vehicle stop on Route 46 East escalated into an arrest Monday morning after a driver allegedly became uncooperative and assaulted officers, according to the Denville Police Department.
Police said the incident occurred on December 15, 2025, at approximately 8:47 a.m. near Franklin Road, when officers conducted a traffic stop for an alleged cell phone violation.
During the stop, the driver—identified as Nicholas Piolli, 35, of Sussex Borough—reportedly refused to cooperate with officers and declined to identify himself. Authorities said officers attempted to de-escalate the situation, but Piolli allegedly slammed his vehicle door against them.
Following a brief struggle, officers were able to take Piolli into custody. He was transported to Denville Police Headquarters for processing.
According to police, Piolli was charged with resisting arrest by physical force, aggravated assault on a law enforcement officer, and obstruction of the administration of law, along with several motor vehicle violations, including failure to use a hands-free device and failure to possess a driver’s license, registration, and insurance.
After processing, Piolli was transported to the Morris County Correctional Facility, where he was held pending a future court appearance.
