The Metropolitan Police has issued a warning for consumers over fraudulent Rugby World Cup 2015 tickets, which went on sale on 1 January 2014.
The Met's Operation Sterling team issued its alert after it uncovered evidence that tickets for the event - held across venues in England and Wales in September/October 2015 - are already being sold on the websites of secondary ticket agents.
Official tickets for the tournament are only available from the official Rugby World Cup 2015 website at rugbyworldcup.com.
The first tranche went on sale on 1 January 2014 to traveling fans, while hospitality packages go on sale on 2 February 2014. Rugby clubs and their fans can buy tickets from May/June 2014, while tickets go on general sale in September 2014.
The Met police has said that consumers should not buy any tickets or packages advertised on any site that isn't the official website.
Over two million tickets are to be sold for the 2015 World Cup, with over one million tickets of them priced at £100 or less and around half a million priced at £50 or less. But tickets for the final at Twickenham on 31 October 2015, are priced at between £150 and £715 a ticket.

The 2011 Rugby World Cup, held in New Zealand, was also hit by a number of ticketing scams. The NZ government had to issue similar warnings after a number of online sellers began offering tickets and packages without authorisation to do so.
