Police are warning drivers today after a woman handed over £20 to a motorcyclist posing as a police officer.

She was driving along the A149, between Heacham and Snettisham yesterday afternoon, when a group of three bikers signalled her to pull over.

One told her he was a police officer and was issuing her with an on the spot fine for failing to wear a seat belt.

The woman paid him £20 in cash but later contacted the police when she became suspicious.

Police spokeswoman Beth Manning said: "Genuine police officers would not take money at the road side but would instead have issued a Fixed Penalty Notice to be paid at a later date.

"Officers carry with them an identity card giving details of their post and collar number which members of the public can use to check their identity with the police.

"If in doubt, contact the police immediately who will be able to verify an officer's attendance."

One of the motorcycles involved in yesterday's incident was black in colour and the other two were white. No further description of the offenders is available.
