A £44,000 Mercedes was stolen off the driveway of the owner's home after two thieves used a hi-tech gadget to start the motor.

The innovative duo used a signal relay device to steal the Mercedes S Class in the middle of the night.

Doorbell footage shows one of the men making his way towards the house while the other stood by the car.

Mindaugas Grizas, 36, and Lukas Zvirgzdys, 18, successfully stole the car for a mere 12 minutes.

When breaking into the vehicle a large engine noise alerted the owner to the theft.
