CHANTILLY ROBBERYTwo Men Sought in Home Invasion Four people were robbed at gunpoint yesterday inside a home in Chantilly, Fairfax County police said. Investigators said the victims, two men and two women, ranging in age from 19 to 21, were inside an unlocked home in the 4100 block of Dawn Valley Court when two armed men entered at 12:30 a.m. and demanded cash and personal items.

Police said the suspects fired two rounds in the air -- possibly from a cap gun or air gun -- before fleeing with cash and other items.

Both suspects are described as black men in their early 20s. One is thought to be about 6-foot-1 and 175 pounds and was wearing black clothing, including a hooded sweat shirt. The second man is described as 5-foot-10 and 175 pounds. He wore dark gray clothing, including a hooded sweat shirt.

Anyone with information about this incident is asked to call Crime Solvers at 866-411-TIPS (8477) or the police non-emergency number at 703-691-2131.

-- Leef SmithPOLICE SEARCH2 Arrested, 3rd Sought After Robbery ReportTwo men were arrested and a third was being sought by police yesterday afternoon after a District police helicopter followed a stolen vehicle into Old Town Alexandria and a search -- involving as many as 20 officers -- ensued. Alexandria police said one adult and one juvenile were taken into custody about noon, about a half-hour after three suspects ditched a stolen Dodge Durango in the 300 block of South Washington Street.

Police said initial reports indicated that the men had just committed an armed bank robbery in Prince George's County. As a result, police -- some armed with rifles -- fanned out across Alexandria's south side in search of the suspects, one of whom was thought to be armed with a rifle or shotgun. Fairfax County police assisted in the search.

Police later said they were unable to confirm the armed robbery report or the existence of a gun and disbanded their formal search for the missing suspect about 1:30 p.m.

-- Leef SmithARLINGTON SCHOOLSSlimmed-Down Budget Is SubmittedArlington County School Superintendent Robert G. Smith yesterday proposed a $410 million budget for fiscal 2008 that includes taking over the operation of Head Start classes, expanding an elementary school foreign language pilot program, updating technology and giving a 2 percent raise to all staff members. The proposed budget represents a 4 percent increase over last year's spending plan, a smaller increase than in recent years.

"County tax revenues are not growing at the rates experienced in recent years because of expected stabilization in the area real estate market," Smith said. Cuts in the proposed budget include the elimination of a supply warehouse and reductions in central administration staff.
