A man has been arrested and charged in connection with a string of burglaries in Loudoun County in which authorities said garage door openers were used to enter houses.

The sheriff’s office said Robert M. Williams-Dixon, 33, of no fixed address, was arrested Monday on 26 charges connected with 11 burglaries in the eastern part of the county.

All of the burglaries were in the Sterling area, north of Route 7, the sheriff’s office said. They said in most cases, a burglar entered homes while residents were sleeping. It was thought, according to the sheriff’s office, that he took door openers from unlocked cars in driveways.

Charges were brought in burglaries that occurred from October 12 to November 3, the sheriff’s office said. A burglar got in through an outside garage door using an opener taken from cars parked in a driveway.

Similar burglaries have been reported in neighboring jurisdictions; the sheriff’s office said it is working with authorities there to determine whether the cases are connected.
