A standoff between police and an armed man in Northern Virginia continued Tuesday afternoon, nearly 24 hours after the man barricaded himself inside a Falls Church home.

According to police, the standoff began about 4:30 p.m. Monday following a domestic dispute at the Hillwood Avenue home.

As of about 3 p.m. Tuesday, about six blocks of Hillwood were closed by police, according to Falls Church police.

The man, who police have said is alone, barricaded himself inside the home and has refused to come out despite efforts by officers from several police departments to convince him to leave.

"That is the goal here — that no one gets hurt,” said Susan Finarelli, a Falls Church police spokeswoman. “Time is the name of the game at this point.”

Officers from Falls Church, Fairfax County and Arlington County, as well as a SWAT team, have been trying to negotiate with the man, police siad. Authorities say they have turned off the gas to the home, knocked out the windows, and tried forcing the man out of the house with a ”gaseous, non-lethal substance.”

Finarelli declined to detail police strategies further.
