Busy day for Olympic ticket sales
The start of the second wave of Olympic ticket sales has been "busy", London 2012 organisers have said.
By 3pm on Friday football, volleyball, wrestling, weightlifting and boxing were among the sports which still had seats available.
Anyone who has applied for tickets will find out if their request has been successful in the next 48 hours.
Details of the amount of interest are still coming in to the London 2012 organisers who opened the second chance sale at 6am, exclusively for 10 days to the 1.2 million people who had completely missed out on tickets.
The scramble for tickets, available on a first-come first-served basis, started with fresh frustration. London 2012 called on sports fans to have some patience as the system slowed with the surge in demand as would-be buyers went online.
The are 2.3 million tickets up for grabs in this round of sales but 1.7 million are for football.
Many people who had risen early to try to get the best tickets failed to get their online applications to go through. Instead they were directed to a webpage saying: "We are experiencing high demand. You will be automatically directed to the page requested as soon as it becomes available. Thank you for your patience."
Even some who got to the stage of requesting tickets and providing their bank card details were then told: "Sorry, we cannot process your request. Please try again later."
A London 2012 spokesman said: "The system is working, it has not crashed. Due to high demand some people are being held outside the system. For those in the system it is working and transactions are going through, but we are having to hold some people back from going through the site due to high demand."
There had already been sell-outs for 21 events including the ceremonies, diving, swimming and tennis in the initial sale.
