Police have issued a warning after a motorist was targeted by robbers on being flagged down by a lone woman at the side of the road.

The 28-year-old male driver, who pulled over in Kingsley Road, near Frodsham, got out but was then grabbed by a man who demanded his keys and mobile phone. A struggle followed in which the motorist suffered a slight scratch to his body and the offenders fled empty-handed. No weapon was seen or used.

Police say the incident happened between 9-10am last Tuesday (September 16) but was not reported until Sunday.

Detective Constable Stuart Needham of Chester CID said: “Fortunately the victim only suffered a slight injury as a result of the incident but he was left shaken by his ordeal. We are appealing for information from anyone who was in the area around the time of the incident who may have witnessed anything suspicious to please get in touch.”

Police say the woman offender is described as being olive skinned, about 5ft 4in tall, aged between 25 and 30, with dark hair which was in a ponytail. She was wearing a green tracksuit with a yellow trim.

The male offender is also olive skinned, between 5ft 10in and 6ft tall, aged between 25 and 30, with dark hair. He was wearing a black tracksuit with dark coloured shoes and was unshaven. He was not believed to have been a native English speaker.

Cheshire Police remind lone drivers to be wary of anyone who attempts to flag them down “under suspicious circumstances”.
