Car dealers across West Norfolk are being warned to be vigilant following several incidents in which vehicles have been stolen from garage forecourts.
The latest incident happened at premises on Lynn Road, Swaffham, between 8.30am and 9.15am on Monday, when a man asked to look at a dark blue Vauxhall Astra.
The owner left the man to look at the car before he drove off and failed to return.
The theft follows a similar incident in Austin Fields, Lynn, last month, when a black Ford Ka was stolen while a member of staff was distracted by answering a telephone call which turned out to be a wrong number.
That incident happened between 9 and 9.30am on Monday December 29.
And two other cases have also been reported in Caister and Yarmouth in recent weeks.
Supt Roger Wiltshire, of Norfolk Police, said officers were looking into the possibility that the thefts may be linked.
But he added: “I would urge car dealers, or anyone who is selling a car privately, to be extra cautious and vigilant when selling vehicles and to take necessary precautions to prevent them becoming victim to this type of scam.”
Anyone with information about the thefts is asked to contact police via the non-emergency 101 number (calls cost 15p).
