Ronnie O'Sullivan's behaviour will be under the closest scrutiny on Tuesday when he resumes his bid to regain the Embassy World Championship title.

O'Sullivan has warned snooker bosses he will not be cleaning up his act in his quarter-final against Nottingham's Anthony Hamilton.

But Sir Rodney Walker, chairman of the World Professional Billiards and Snooker Association, will be watching the Rocket's every move.

"Ronnie is an extremely talented young man who has made a lot of money from snooker," said Sir Rodney.

"He has got a responsibility to act in a certain manner so the younger players coming into the game follow his example.

"There is a disciplinary procedure in place and we will be looking at this. I am also aware of Ronnie's comments in a newspaper and I am disappointed with them.

"Inevitably, because of this, we will be forced to look at the situation."

O'Sullivan's crude hand gestures have over shadowed his opening victories against Stephen Maguire and Andy Hicks.

He claimed victimisation by the media and stormed out of his press conference after a thrilling victory over Hicks.

Coupled with the fracas between Hicks and Australian Quinten Hann, the sport's reputation has been sullied during the first nine days of the tournament.

"Snooker has been renowned for the good behaviour of its top players so I am very disappointed with this," added Sir Rodney.

"There have been two incidents this week that have been unhelpful to the image of snooker.

"I would urge all players to remember that the Embassy World Championship is our showpiece event and they need to behave properly.

"I have already spoken to a lot of players and they all realise the vast majority of their income derives from tournament money generated by broadcasters and sponsors."

O'Sullivan claimed in an interview: "I will keep showing my feelings by swearing and gesturing at the pockets and there is nothing snooker's governing body is going to do to stop me because that is me."
