British rockers Coldplay are fuming after learning that tickets to see them perform in Las Vegas, Nevada, are being sold online for up to 25 times their face value.

The Clocks band sold out their 3 February (06) gig at Sin City's 17,000 capacity MGM Grand in just seven minutes.

Ticket prices for the concert start at $50 (GBP28), but the CHRIS MARTIN-fronted group is livid after discovering some internet sites are selling seats for $1,260 (GBP700).

An insider says, "Coldplay never charge much for gig tickets because they want them to go to genuine fans. They are very strict about it.

"They could charge loads more for them, like many other acts do. But the last thing they want is for fans to be priced out of going to their gigs.

"Unfortunately there is very little the band can do to stop greedy scalpers from buying loads of tickets then flogging them on the net.

"The sites that offer these expensive tickets are not part of the official Coldplay site."
