Four men forced their way into a Sterling home Wednesday night in a home-invasion robbery that authorities believe was targeted.

The incident occurred about 9 p.m. at a home on Ironstone Terrace, when a resident answered a knock at the door and was confronted with four men wearing bandannas that partially covered their faces, according to the Loudoun County Sheriff’s Office.

The men forced their way into the home, and one of them drew a gun, authorities said. Three of them were described as white males, and the fourth as a black male, according to the sheriff’s office.

The men demanded money and valuables, authorities said, and began ransacking the house. Investigators suspect that the robbery was targeted and possibly drug-related. There was no indication of any threat to the community, authorities said.

Anyone with information on the case is asked to contact the Loudoun County Sheriff’s Office Criminal Investigations Division at 703-777-0475. Callers wishing to remain anonymous are asked to call Loudoun Crime Solvers at 703-777-1919. If the information leads to an arrest and indictment, the caller could be eligible for a cash reward of up to $1,000, according to the sheriff’s office.
