Two men were found guilty of drug offences by a unanimous jury.
Jamil Said Jamil, 43, of Conniburrow Boulevard, Conniburrow, and Mohammed Saeed Ali, 44, of Chervil, Beanhill, were each sentenced to four years in prison.
Amersham Crown Court heard that on August 1, 2014, plain clothes officers noticed a suspicious transaction taking place in a parked vehicle, at Lloyds Court in Central Milton Keynes.
A man and a woman got into the rear of the vehicle in which Ali and Jamil were sat in. They completed a seeming drug deal and then left the vehicle and walked away.
Officers followed the vehicle from Lloyds Court after it pulled away. When the car pulled up at a local BP petrol station, officers carried out a drugs search of Jamil and Ali, as well as the vehicle.
Officers located a large number of wraps of both heroin and crack cocaine.
Following forensic analysis and further investigation both men were charged on November 5, 2014.
Both men were convicted on August 2, 2015, on two counts of possession with intent to supply class A drugs.
The pair were also subject to a Proceeds of Organised Crime Act hearing, in which over £2,000 in assets were seized.
Investigating officer, Det Con Graeme Poulton based at Bletchley police station, said: “The sentence handed out and the seizure of assets from Jamil and Ali, show that crime simply does not pay, and if you do lead a life of criminality, then any assets you do have been be identified and recovered.
“I would add that drug dealing will not be tolerated in Milton Keynes and our officers will use a variety of methods in order to disrupt this activity.”
