Road police in Surrey arrested two people they said tested positive for cocaine after they were stopped in a hair-raising pursuit on Valentine's Day (February 14).

Surrey RPU took to Twitter to describe the dramatic pursuit and arrests, which occurred after a car they were following refused to stop.

They also posted a short video showing moments of the chase when the fleeing car, a Ford Fiesta, attempted to escape pursuing police.

A spokesperson for the roads policing unit said that they had initiated the pursuit after they identified the car to be stolen and on "cloned (number) plates". 

"Earlier this evening we found this stolen Fiesta on cloned plates.

"The driver failed to stop and we pursued it.

"We deployed the #RevengeOfTheHedgehog and punctured its tyres, the pursuit ended a minute later with both occupants being arrested," the short statement said, referring to the stinger device or 'hedgehog' used by road police to stop cars by puncturing their tires.

It later emerged that the driver tested positive for cocaine and cannabis after the police used a "drugs wipe" test on them following the arrests.

"driver refused to provide a blood sample in custody after a positive @DrugWipeUK test for Cocaine and Cannabis.

"They remain in custody while investigations continue.

"Great teamwork with our Armed Response colleagues," the spokesperson added.
