London 2012 Olympic tickets available abroad
Foreign websites, claiming to sell tickets for the London Olympics, have been jammed, after it was revealed that UK citizens could buy tickets direct from other EU countries.
But Olympics organisers are asking fans to be extremely cautious about touts.
Meanwhile, people who bid for tickets from the official UK site are still waiting for the money to be taken.
Paul Lewis of Radio 4's Money Box tells BBC Breakfast that the public should be very wary of buying tickets from unauthorised foreign websites.
