ESSEX Police are warning members of the public of a potential scam involving people selling their vehicle.

Suspects are responding to adverts for vehicles advertised online and in newspapers under the illusion of buying the car. The false buyers are then asking to see if the spare key is working by asking the driver for it. When the spare key is handed over and tested, a second key is given back to the owner whilst the working spare key is retained by the suspects.

This key may later be used to either steal possessions from the vehicle or to take the vehicle itself.

Please remain vigilant when selling your vehicle and ensure that you always remain in possession of the keys for the vehicle.
