Reigning world champion Ronnie O'Sullivan on Tuesday alleged that Stephen Lee may not be the only top-level snooker player to have taken part in match-fixing.
Lee, a former world number five, was found guilty of match-fixing on Monday over matches in 2008 and 2009. He could be handed a lifetime ban at a hearing next week.
O'Sullivan claims Lee's case may only be the tip of the iceberg, and accused the snooker authorities of not doing everything in their power to bring corruption in the sport to light.
"I've heard there's many more players who throw snooker matches .. I suppose Steve lee was just caught out," he wrote on Twitter.
"I just love putting it out there bring it all out in the open.. Nothing like a bit of transparency is what I say..
"No need to worry if you got nothing to hide. But plenty of people have got loads to hide. That's why there is no free speech. There (sic) hiding."
He added: "They will prob fine me for talking about it.. They don't like you doing that.. Like to keep things under the carpet.."
World Snooker chairman Barry Hearn reacted by saying that his organisation would ask O'Sullivan to expand on his allegations.
"If he has names and he knows of incidences, he has an obligation and a duty to report them and failure to do so will put him in breach of his player's contract," Hearn told Britain's Press Association.
"World Snooker will be writing to Ronnie to say that under his player's contract, it is his responsibility to report any incidences he's aware of and failure to do so would lay him open to a charge of bringing the game into disrepute."
