London 2012: IOC Begins Olympics Tickets Investigation
The International Olympic Committee has begun an investigation into claims that Olympics officials and agents breached rules on London 2012 ticket sales.
The IOC has held an emergency meeting of its ruling executive board via conference call after claims by the Sunday Times.
The IOC has referred the allegations to its independent ethics commission.
The organisation could also review how Olympic tickets are distributed among member countries.
The Sunday Times submitted a dossier of evidence detailing claims that Olympic officials and agents had been caught selling thousands of tickets on the black market for up to 10 times their face value, says BBC Sports News correspondent James Pearce.
The newspaper alleges that its two-month investigation found corruption involving people representing 54 separate countries.
