UPDATE: Clifton Stand-Off Resolved Peacefully, Police Say

UPDATE: 3:55 p.m.: Fairfax County Police say a stand-off at a Clifton residence was resolved peacefully Monday afternoon, after about six hours that tied up two roads, Henderson Court and Henderson Road.

The distressed male,20, was taken into custody, police said, and he'll be evaluated and given any services he might need.

Police said earlier that the young man had some kind of a weapon, possibly a gun, and that other family members in the home left without incident before the stand-off began with police just before 10 a.m. Monday. Family members had contacted police shortly after 9 a.m. A SWAT team mobilized outside the home in Fairfax County's Clifton area Monday morning. Personnel from Mobil Crisis and from the Fairfax County Fire and Rescue Department were also called to the scene.

Negotiations continued until the man inside the home surrendered and was taken into custody shortly after 3 p.m., police said. There were no injuries. A temporary detention order was obtained for the man who will be evaluated and provided the services he may need.

Police posted this message at about 11:30 a.m. Monday:

The roads there remain blocked -- Henderson Court and Henderson Road at that intersection (see map below) throughout the day. The home is located in the 11900 block of Henderson Court.

Neighbors were notified by the Department of Public Safety Communications (DPSC) through the use of a reverse 911 call.
