Six people have been arrested after a second investigation into football match-fixing was launched following reports that a player agreed to rig a League Championship game in return for cash.
Britain's National Crime Agency confirmed on Sunday it was examining the allegations after receiving information from The Sun On Sunday.
The newspaper said an undercover reporter met one player who claimed another agreed to deliberately earn a booking in a recent match in the second-tier of English football in return for a 30,000-pound payout.
"An active NCA investigation is now underway and we are working closely with the Football Association and the Gambling Commission," the NCA said in a statement. "Six people are in custody and are being questioned by NCA officers. We cannot comment further at this stage."
According to the newspaper, the footballer, identified as former Portsmouth and Nigeria defender Sam Sodje, also claimed he could fix Premier League games and added he was capable of rigging matches at next year's World Cup.
