The betting firm involved in last year's 'Piegate' incident has had its licence to offer gambling in Britain reviewed by the Gambling Commission.

The Commission launched an investigation after Sutton United goalkeeper Wayne Shaw ate a pie during his club's FA Cup fifth round tie against Arsenal last February.

It emerged that Tabcorp UK Limited, trading as Sun Bets, had offered odds of 8/1 on Shaw eating a pie during the match, and the goalkeeper was fined £375 and banned from playing for two months by the Football Association.

Richard Watson, Gambling Commission programme director, said: "Vulnerable customers were able to gamble with Tabcorp UK, despite choosing to self-exclude. This is not acceptable. Gambling firms must ensure the systems they have in place are protecting their customers effectively.

"Novelty betting markets, such as the market Tabcorp UK offered on last year's FA Cup tie between Sutton United vs Arsenal, may seem like a bit of fun but the consequences were serious - with the potential to encourage someone to commit a criminal act or breach a sports governing bodies' rules."

Tabcorp UK is to have new conditions attached to its gambling licence and pay £84,000 to socially responsible causes.

The Commission's investigation revealed that Tabcorp UK failed to properly manage the risks associated with offering 'novelty' bets and that it had allowed more than 100 self-excluded customers to open duplicate accounts and gamble.

Shaw ate a pie on the substitutes' bench as Sutton lost to the Gunners, and the charge of influencing betting markets - which Shaw denied - was found proven at an Independent Regulatory Commission hearing last September.

The stunt took place in the 83rd minute of the match, which Arsenal won 2-0, and led to Shaw's sacking by the club.

"My world fell in," Shaw told BBC Radio 5 Live in May. "I was in tears. I had never been sacked in my life.

"It's on my mind every day, it probably will be for along time. I've been through depression. I wasn't sleeping right, I could feel myself getting stressed. And I've still got that knot in my stomach.

"The following afternoon it was a situation where I either resigned or they sacked me.

"No one asked for my side of the story. The club's knee-jerk reaction was that they wanted nothing to do with it.

"I haven't made any money and my friends haven't made any money. I probably got carried away, after a whole career of having the mickey taken out of me. That was all it was meant to be."
