Police in Johannesburg have been called in to control angry crowds trying to buy tickets for the Football World Cup, after the computerised ticketing system crashed for several hours.
The system also collapsed last month when over-the-counter sales first began in South Africa, the BBC reports.
The sport's world governing body FIFA has been releasing unsold tickets slowly, but on Friday it said the last 90,000 seats, including for the final, would go on sale.
Large queues gathered outside the sale centres and, as the doors opened, the system crashed.
With many people having waited all night, police had to be brought in to control the queues.
The tournament begins on 11 June.
