On the A3 motorway in the direction of Luxembourg City, just before the Croix de Gasperich, a car overturned in a dramatic car crash on Monday evening at around 5pm.
The driver of the crashed car fled the scene just before emergency services arrived. The driver's actions prompted a widespread search for the person, not only because of the accident but it was also was not known whether they had sustained any injuries.
The search was finally broken off at around 9pm, with the driver still unaccounted for.
The scene of the crash had been cleared by then and the car had been towed.
On Monday evening, the public were advised to report any person who appeared to have fresh injuries to their face, and may have been close to the Croix de Gasperich, to the police and not to pick up hitch hikers.
