A police officer entrusted to take a stolen Porsche Carerra to a compound lost control and wrecked the car.
The £60,000 vehicle is likely to be a write-off. It spun into oncoming traffic and smashed through 100ft (30m) of roadside fencing in Kent.
A 39-year-old officer had been asked to take the silver Carerra, which has a top speed of 174mph and can go from 0-60mph in five seconds, to the compound, where it was to be examined.
He is believed to have lost control of the left-hand-drive car, which had been reported stolen by its Belgian owner, as he was overtaking another car on a single carriageway.
It ended up in a field just off Patrixbourne Road, near Canterbury. The driver suffered cuts and bruises but did not need medical attention.
One police source said: "He was only slightly injured but his ego was damaged more."
Yesterday a Kent police spokesman said an investigation had been launched.
"The car was being taken to a secure compound for forensic examination when the accident happened." It is thought the officer was not a routine patrol officer.
The car was so damaged that police insurance valuers expect it to be a write-off.
Police are appealing for witnesses to the accident, which happened in good weather on Tuesday afternoon.Reuse content
