Fairfax County Police say that a man is in custody after he barricaded himself inside a car on the fourth floor of the parking garage near the Fairfax County Courthouse .
According to News4's Darcy Spencer, police received a call from either the man or members of his family at around 3:30 p.m. Police say the man threatened to harm himself during the course of the call and insinuated that he had at least one weapon, which prompted the response.
Responders set up a wide perimeter around the area of the Fairfax County Judicial Center, which is located at the intersection of Judicial Drive, Virginia Route 236, and Virginia Route 123. All those streets were blocked for several hours on Saturday evening.
Police announced the man was in custody after he surrendered peacefully shortly before 9:30 p.m. The car was examined by a bomb squad robot, which found no trace of weapons or explosives. Authorities did not clear the scene until shortly before 11 p.m.
The man, who is 54 years old, had a loaded shotgun, News4 confirmed.
