Liverpool and Aberdeen men admit supplying heroin
A drug trafficker continued in his efforts to evade the police even after the tyres on his car were blown out by spikes strung out across the road.
Lawrence Mitchell, 26, of Liverpool, eventually lost control of the Audi when the tyres came off on the A9, near Aviemore, in the Highlands.
The High Court in Edinburgh heard that police had been watching Mitchell and Louis Butler, 25, from Aberdeen.
Their arrests led to the seizure of heroin potentially worth £64,570.
Police started monitoring Mitchell and Butler after a tip-off about drugs being run between Liverpool and north east Scotland.
Advocate depute Peter McCormack told the court that Butler had rented a static caravan in Fochabers.
On 22 March, officers were told that an Audi previously seen at the caravan was heading off to pick up drugs.
Police closed part of the A9 near Perth to stop the car.
Mr McCormack said as the Audi was signalled to halt the car accelerated away, avoiding the police vehicles in front of it.
The advocate depute said: "Mitchell repeatedly drove on both sides of the carriageway in an attempt to pass the police cars and was driving at speeds of between 100mph and 130mph.
"Eventually a 'Stinger' spike strip was deployed resulting in the two front tyres of the Audi being deflated."
After Mitchell's car came off the road, police found heroin in a rucksack and more of the drug in the caravan and on Butler.
Both men pleaded guilty to being concerned in the supply of heroin in February and March this year.
Mitchell also admitted dangerous driving.
They will be sentenced at the High Court in Glasgow next month.
