Thousands of people sat ready and waiting at their computers this morning, hoping to secure tickets to the Olympic Games in the third round of ticket sales.
For those who'd tried and failed twice to get tickets, another window of opportunity opened at 11 o'clock.

Games organisers and police say they're doing everything they can to ensure the tickets go to real sports fans, but is that a realistic ambition?
