A London motorist caught doing a record 172mph in his Porsche on a rural A-road has been jailed for 10 weeks.

Tim Brady, 33, of Harrow, became the fastest speeder ever caught by a British speed trap when he admitted one count of dangerous driving.

He was caught in January in a random speed check on the A420 near Abingdon, Oxfordshire, driving a £98,000 3.6-litre Porsche 911 Turbo, Oxford Crown Court heard.

The previous record for the fastest car clocked by a speed camera to result in a conviction was 156mph - in 2003 by Aberdeen car dealer Jason McAllister on the A90 between Aberdeen and Dundee.

Brady was given a three-year driving ban and ordered to pay £474 costs.

Judge David Morton Jack told Brady: "Your driving was criminally self-indulgent and utterly thoughtless of the danger you might be creating for the innocent."

Brady was stopped by a police constable holding a speed gun.

He resigned a short time after the incident from his job as a delivery driver at Helphire, a luxury car hire firm with a base at Kingston Bagpuize, near to where he was clocked.

He took the Porsche from his workplace without permission on January 27, the court was told.

John Reilly, for Brady, said in mitigation that his client had later described his 172mph drive as "foolhardy, stupid and done in a moment of weakness".
