Township officers had gone to the home on Vail Place off Campgaw Road -- barely a half-mile from the Bergen County Police and Fire Academy -- for an unspecified reason shortly before 3:30 p.m. April 22.
A Bergen County Regional SWAT team was summoned, along with a Regional Crisis Negotiation Team.
The 49-year-old man emerged from the home and was taken into custody without incident shortly before 4:30 p.m., they said.
It wasn't immediately clear whether he'd be taken to Bergen New Bridge Medical Center in Paramus or have a private evaluation.
