Tickets are being illegally marketed for a Led Zeppelin comeback tour even before the reunion has been confirmed.

Hotel and ticket packages for shows at London's O2 Arena are reportedly being sold for more than £269.

A reunion tour by the 1970s legends has been rumoured but denied by former members.

Harvey Goldsmith, a top promoter, has issued a statement warning fans about the ploy and about touts in general.

He declared: "There have been at least four events advertised which I suspect either don't exist or where no tickets are on sale or indeed dates finalized.

"These are the very people whom our industry has spent over a year trying to convince the Department for Culture, Media and Sport (DCMS) to instigate outlawing."

Goldsmith added: "There are NO packages or tickets for some of the events advertised at all, nor do some of the events even exist. We are concerned that the public will be fleeced. The bottom line is that unless official adverts have appeared for concerts, tickets are not on sale. Do not buy from unauthorized sources."

One of the companies concerned has now been reported to DCMS.
