Returning from two weeks' holiday, Sandra Yarwood had no idea that anything was amiss with the small, black Volkswagen Golf still parked in the street outside.

Until, that is, the traffic violation notices started pouring through the letter box.

The media consultant from Earl's Court in London, was astonished to receive no fewer than 32 separate £90 fines from seven different local authorities, accompanied by claims she'd driven in bus lanes, parked illegally and violated no-traffic zones across the capital.

Ms Yarwood, who was in Canada at the time of the offences, soon realised she was the victim of a registration-plate cloning scam now sweeping Britain.

Thousands of motorists a year find that fraudulent copies of their number plates have been attached to completely different vehicles, and then used to avoid traffic fines or even commit crime.
