A drug dealer from Maidstone has been jailed after filming himself chasing after a police car on the M20 at 120 miles-per-hour.
Princely Imara used his phone to film the police car on an emergency call ahead of him - and his speedometer as it showed the car way over the speed limit.
Inspector Martin Stevens from Kent Police's Road Policing Unit told ITV Meridian he has never known anything like the "shocking" incident.
Imara was not caught until a later date, when he was pulled over for driving erratically on the M2 near Sittingbourne.
He then sped off - this time reaching speeds of 130mph - but crashed into a barrier near junction five at Stockbury.
It was only then that police found his mobile phone and the footage of his previous chase.
Imara has now been jailed for four-and-a-half years for dangerous driving and a string of other offences - including drug dealing and burglary. He has also been disqualified from driving.
