A PORSCHE has been stolen from its female owner after a fellow driver tricked her into pulling over before threatening her and escaping in the expensive vehicle.

Police are appealing for information following the incident on the A140 at Stoke Ash yesterday evening.

The Porsche was being driven by its owner, who was driving on the northbound carriageway at around 6.10pm, when another car flashed its lights in at her.

The female passenger of the other car then pointed at the front of the Porsche.

The victim stopped in a nearby layby to check if there was a problem and a man then threatened her, before taking the sports car and driving off towards Diss with the other car following.

The woman was shaken but unhurt and ran to a nearby pub to raise alarm.

The Porsche is a blue Boxster S, registration LY10CUC. Also stolen were two bags containing money, a watch, a mobile phone and clothing.

The man has been described as white, in his early 30s, with blond hair and straight fringe. He was wearing a dark coat.

The female passenger is believed to have dark hair which was tied in a scruffy ponytail.

Detective Inspector Karl Smith said: “Such incidents are rare, but I would urge all drivers to be aware of their surroundings and keep windows and doors locked when their vehicle is stationary. If you are being signalled to stop by another vehicle, only stop if you are safe and happy to do so.

“Call police if the other driver’s behaviour is threatening or putting you at risk, or drive to the nearest police station.

“Officers are working with neighbouring police forces to trace the Porsche’s journey after it was stolen. I want to hear from anyone who may have seen the car on the A140 or further afield in Norfolk or Suffolk from around 6.15pm onwards last night.”

Calls should be made to DC Ben Clark at West Suffolk CID on 01473 613500 or Crimestoppers on 0800 555 111.
