Police arrested two suspected drug dealers after tracking their number plates.
Yesterday evening (Thursday) two officers were on a plain clothed foot patrol when they spotted what they thought could be a drug deal taking place from a car.
The car drove off, but the officers were able to get the number plate.
Then, using ANPR (automatic number-plate recognition) systems, they were able to pinpoint where the vehicle had travelled and, with the help of colleagues, managed to stop it in Whittlesey Road, Stanground.
The two occupants - a 21-year-old man and a 17-year-old - were both arrested on suspicion of possession with intent to supply Class A drugs and possession of a weapon.
The 21-year-old has since been further arrested for driving without a license or insurance.
They remain in custody at Thorpe Wood Police Station.
