A motorist has been arrested on suspicion of driving at 172mph on a rural road.
Police, who had been using a speed gun on a bridge over the A420 near Abingdon, Oxfordshire, on Saturday, detained the 33-year-old man.
The man has been released on police bail until 17 February.
Helphire, a car lease firm in Abingdon, said an employee who had "borrowed" a £98,000 Porsche 911 Turbo without permission had since resigned.
Not that I condone those kind of speeds, but ......if you are going to quit your job, I can't think of a better way to do it!
