WASHINGTON — An armed man who had barricaded himself for nearly 10 hours in Herndon, Virginia, on Sunday surrendered and was arrested, police said at around 2 p.m.

No one was injured during the incident.

The man was identified as Anthony Moaf, 21. He is in custody, but police said he became ill on the way to a psychiatric evaluation and was taken to the emergency room.

Moaf faces charges for reckless handling of a firearm, Fairfax County police said.

Police had been working to resolve the barricade situation with Moaf since around 4 a.m. Sunday. Police deployed their police robot and gas grenades when Moaf did not follow their commands to surrender.

Officers initially responded to a report of a man threatening to kill family members at around 4 a.m., police said. Two adult family members made it out of the house uninjured.

Moaf also threatened to shoot at first responders and police said they heard at least one gunshot in the house at around 6 a.m. Police stayed in contact with Moaf after the gunshot but the barricade continued for several hours.

“They did hear a shot or what they thought was a gunshot around 6 a.m. it was not directed at officers, and they have had contact with the man since then,” said Officer Reem Awad with the Fairfax County Police Department while the barricade was ongoing.

The incident happened on the 13200 block of Ladybank Lane in Herndon. Those who live in the area were asked to shelter inside their houses, away from doors and windows. Some residents who had left their houses were unable to get back because of the situation.

Mark Bucko, a resident of Ladybank Lane, left his house Sunday morning at around 6 a.m. and was unable to return home due to the barricade.

“It’s kind of a surprise. I mean it’s a quiet neighborhood, great neighborhood. I’ve been here since ’94 and it’s been a great place to raise a family and everything. So surprised to wake up to all this excitement but police seem to have it under control, trying to keep everybody safe and hopefully get a good resolution of the situation and that’s all we’re hoping for,” Bucko said while negotiations were still going on.

Police asked people to stay far away from the area until the situation was resolved.

“We thank the community for their support and cooperation in staying indoors until this was resolved. We are glad this barricade ended peacefully and without injuries to anyone,” police said in a news release announcing Moaf’s arrest.
