As if travel was not difficult enough during the recent harsh weather, a man told authorities Tuesday that the driver of an airport shuttle vehicle brandished a weapon and demanded money.

The Loudoun County sheriff’s office said a shuttle driver was taken into custody and charged with robbery. He was identified as Jesus A. Jospehson, 52, of Hyattsville.

The sheriff’s office said the passenger was picked up in the District and driven to Loudoun, reportedly to pick up another person before going to Reagan National Airport.

Some time before 6 a.m. in the Sterling area, the sheriff’s office said, the driver brandished what was described as a sharp blade and demanded money.

The passenger fled.

The sheriff’s office said Jospehson was being held at the county adult detention center.

The shuttle service was not identified by name. No injuries were reported.
