UPDATE 5:54 P.M.:
Police activity in the Greenbriar neighborhood is coming to a close, as authorities realize that a 911 call about a possible armed man in a motorhome was a false alarm.
First responders at the scene said that the incident was related to a medical condition.
The confusion arose from a reference to a gun case in the 911 call.
No one was in any danger and the man in the motorhome posed no danger to the public, authorities said.
Fairfax County Police are currently on the scene in the unincorporated Greenbriar neighborhood, preparing to approach a suspicious motorhome witnesses fear is occupied by an armed man.
According to police public information officer Don Gotthardt, the department received a call shortly after 2 p.m. from people in the 12800 block of Melvue Court - a cul-de-sac - about the suspicious vehicle and man.
"We received an initial report that the occupant might be armed in some way," Gotthardt told Patch.
Gotthardt said the department sent several patrol cars and motorcycles into the area, and that the officers were contacting residents in the area to warn them about the potential, and as yet unverified, danger.
Fairfax County Public Schools spokesman John Torre said a handful of students at Greenbriar East Elementary School were being held in the building "until police activity concludes."
The majority of the school's students followed normal dismissal procedures this afternoon, Torre said.
However, Gotthardt said students who reside in the Melvue Court block where officers are now are being asked to remain at the school until officers are sure residents are not in danger.
Gotthardt said officers have not seen any movement inside the silver motorhome yet, and that they are waiting for additional units to arrive on the scene before they attempt to contact the occupant.
"We want to make sure we have good containment at the scene before they attempt to contact him," he explained.
Patch will continue to update this story as more information becomes available.
