Investigators probing Granit Xhaka's booking in Arsenal's Premier League win at Leeds last season are looking into an alleged criminal conspiracy involving the Albanian mafia and an ex-professional footballer who has been convicted of match-fixing.
Sportsmail revealed in June that the FA's inquiry into Xhaka's bizarre yellow card for time wasting last December was passed on to the National Crime Agency, who lead the UK's fight against serious and organised crime.
The FA's investigation was triggered by suspicious betting patterns that emerged towards the end of Arsenal's 4-1 win at Elland Road, with £52,000 staked on Xhaka being booked in the final 10 minutes of the game.
