Unauthorised agents have been offering Dire Straits and Mark Knopfler shows to unsuspecting promoters across worldwide.
A spokesman for Knopfler has issued a warning to promoters following a flurry of cases in South America recently - and stressed there are no plans for any Dire Straits' shows.
"There are no plans whatsoever for Dire Straits shows, and any Mark Knopfler shows should be booked only through Brent Smith at William Morris for North America, and Andrew Zweck at Sensible Events for the rest of the world," said a statement issued on behalf of the singer.
Last year, con artists attempted to dupe promoters by posing as representatives of Aerosmith and Pearl Jam in a fake email scam.
