A man has been jailed after he was found asleep at the wheel before driving at police officers when they woke him up.

Derek Muir has been sentenced to 18 months in prison after racking up his seventh conviction for dangerous driving, his 14th for driving while disqualified and his 14th for driving without insurance.

Muir was disqualified from driving for life in 2014 after he was convicted of stealing a vehicle and driving it dangerously while banned.

However, despite the ban he was found slumped at the wheel of a Seat Leon car on Emmock Road near the A90, Dundee, by a concerned motorist who was blocked by his stationery car.

The driver alerted police who turned up and found Muir still asleep.

Officers roused him and while they checked his details on police computer systems, Muir stuck the keys in the ignition and sped off.

Fiscal depute Charmaine Gilmartin told Dundee Sheriff Court Muir managed to squeeze his car between a police van and a grass verge before driving at speed towards officers getting out of another vehicle.

The 39-year-old, a prisoner at HMP Perth, pleaded guilty on indictment to driving dangerously, without a licence and without insurance on December 19 last year, and to possessing diamorphine, cocaine, amphetamines and cannabis resin on December 26.

Sheriff Alastair Brown jailed Muir for 18 months and banned him from driving for nine years.

He said: "In view of your lifetime disqualification that may be academic."
