Brazen thieves stole a police car and drove it 230 miles before they were stopped by a stinger.
The marked car was taken from Camelford Police Station in Cornwall before it was finally stopped on the M4 close to Slough, a journey of almost four hours.
A spokesperson for Devon and Cornwall Police said: "During Friday evening a burglary occurred at Camelford Police Station, during which the keys were taken to a marked police car.
"The car was taken and later spotted on the M4 heading East.
"Officers used a stinger device to bring the car to a stop near junction 7 and arrest the occupants."
A 23-year-old man and a 31-year-old woman, both from Camelford, were arrested at the scene and later charged with 15 offences between them including burglary, theft, and dangerous driving.
