Loudoun County authorities are searching for four men involved in a home invasion robbery that occurred shortly before midnight Thursday in Sterling, according to the Loudoun County Sheriff’s Office.  

The four suspects, all of whom wore dark hoodies and had their faces covered, entered the home on Gladstone Drive through an unlocked basement door, according to the Sheriff’s Office.

Two of the suspects were armed with guns, while the other two carried baseball bats, authorities said.

The robbers demanded cash from a 32-year-old Sterling man who lives at the home along with three roommates, according to Liz Mills, spokeswoman for the Loudoun County Sheriff’s Office.

The resident was not injured during the robbery, and the suspects fled with a small amount of cash, authorities said.

Loudoun deputies responded to the scene after they were called by the victim’s roommates, who were upstairs at the time of the robbery, authorities said.

The deputies conducted a search with the help of a canine unit but did not find the suspects, according to the Sheriff’s Office.

 The case remains under investigation by the Loudoun County Sheriff’s Office Criminal Investigations Division. Anyone with information regarding this case is asked to call Investigator C. Cunningham at 703-777-0475.

If the caller wishes to remain anonymous, please call Loudoun County 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.
