Tracker has played a vital role in helping the police recover two stolen Mercedes, which after being stolen from one address were recovered from containers on two different ships that were destined for Hamburg.

One had already started its voyage and the other was still docked at Portsmouth harbour.

A customer hired a Mercedes from Licensed Carriage Hire (LCH), based in Elstree, Hertfordshire, as his own vehicle was going into the garage for repairs.

But that night both his own and the LCH vehicle were stolen from his drive after thieves broke into his house and stole the keys for both vehicles.

Fortunately, the LCH vehicle was fitted with a Tracker unit and the Mercedes was found in a container on a ship preparing to leave to Hamburg.

As the police suspected there may be other stolen vehicles on a ship that had already left the docks, they called ahead to their colleagues in Hamburg and the containers were held and returned to the UK. Once the containers were opened, police found the LCH customer's Mercedes.

Tracker’s stolen vehicle recovery systems work like an electronic homing device. A covert transmitter is hidden in one of several dozen places around the vehicle.
