T in the Park weekend camping tickets with a face value of £115 began appearing on online auction sites on Friday with some on offer for as much as £3500 a pair.

But folk buying them could be refused entry to the event, organisers warned.

Tickets for the event, headlined by The Who and the Red Hot Chili Peppers, sold out in 56 minutes on Friday and since then auction site eBay has become the market place for sellers.

The Arctic Monkeys, The Strokes, Primal Scream, Kaiser Chiefs and the Ordinary Boys are among the other acts that will perform at Balado near Kinross on July 8 and 9.

Touts on eBay are selling pairs of weekend camping tickets for £3500, £1000 and £750.

Music fan Andy Barbour of Dundee said, “I’d be very disappointed if a similar situation happened at Camperdown Park.

“A lot of the people that missed out on T in the Park tickets are the people that go year-on-year and helped build its reputation as the best festival in the world.

“Those people are losing out to greedy touts that are only in it for profit. It’s a real slap in the face.”

Jennifer Cosgrove of Dundee was another fan that missed out.

“I missed out, but that’s life,” she said.

“However, I can’t believe people bought tickets in the morning and had them on eBay the next day.

“To me it is just greed. Fair enough if a mate can’t make it and you’re selling the ticket on, but buying simply to sell is just depriving true music fans of their tickets.”

Festival organisers have stressed tickets should not be bought from touts.

Organiser Geoff Ellis said, “Additional security measures are in place this year. Tickets are limited to two per person, and they will be named and scanned on entry to the event.

“We also recommend fans don’t buy from unofficial sources to ensure they do not fall victim to ticket touting or fraud. If the source is not legitimate, there is no guarantee the tickets are genuine.

“Tickets will not be posted out until 10 days before the festival and they will have names on them.”

The ticket touts of today no longer have to hover around outside concerts and festivals trying to sell their tickets.

Auction sites such as eBay have become an easy and simple way to sell their wares.

eBay insists it was doing nothing wrong by allowing the sales, arguing it was “a fundamental right for someone to be able to sell something that is theirs”.

Although the law bans the sale of certain sports tickets, including those for most football matches, there are no regulations covering concert tickets.

An eBay spokesperson said, “It is a fair and reasonable consumer right for the purchaser of a ticket to resell that ticket unless the resale would be unlawful.”
