The Loudoun County Sheriff's Office is investigating an attempted robbery of a McDonald's in Sterling.
Authorities say four masked men - one armed with a knife - walked into the restaurant in the 20800 block of Pidgeon Hill Drive shortly before 12:30 a.m. Thursday. The employees managed to escape, leaving the suspects, described as Hispanic males, empty-handed. The four men then fled the scene.
Anyone with information is asked to call police at 703-777-0475. Callers may remain anonymous. Officials are offering a $1000 reward for information that leads to an arrest and indictment.
