Police are urging residents in the Thetford area to remain vigilant after a suspected rogue trader incident.

The warning comes after workman cold-called at an home in Whitepot Road at Methwold Hythe offering driveway services.

The home-owner agreed to have work carried out, but the workers returned later and demanded more money that what was originally agreed.

It follows a similar incident yesterday in Great Dunham where workers demanded more money for work than first agreed.

Police are urging residents and business owners to be on their guard against cold-callers.

Norfolk County Council's Trading Standards Officers say residents should never agree to have work done, or buy goods from, someone who calls unannounced at their door, or approaches them on the street.

Often such traders don't provide full names, trading addresses or contact telephone numbers, resulting in it being virtually impossible to trace them if there are any problems with the work or goods.

Such traders often ask for cash up-front, and don't offer the entitled seven-day cancellation rights.
