Thames Valley Police officers have arrested two people on suspicion of theft after they discovered with a huge quantity of fuel in the vehicle the suspects were travelling in.
The officers stopped a car on the M40 near Beaconsfield on Tuesday 5 May. The vehicle was carrying 500 litres of diesel that the occupants of the car could not account for.
The driver was also driving without a driving licence, insurance or an MOT, and the vehicle also had false licence plates.
A 28-year-old man and a 24-year-old woman, both from Hillingdon, London, were arrested on suspicion of theft and have been bailed until 6 June.
