The head of the International Cricket Council's Anti-Corruption Unit has dismissed claims that his investigation has achieved little after Mark Waugh became the latest player to be cleared.

Condon said that his team, with the help of other investigators around the world, have significantly reduced the amount of corruption within the game.

They thwarted an attempt to fix this summer's England v Pakistan series as well as continuing to explore past allegations that have yet to be made public.

"We are still working on other cases that at present are not in the public domain," Condon told the Daily Mail newspaper.

"There are individuals who are in our sights and they are not in any way linked to the names that came out in India's CBI report."

Allegations

Mark Waugh followed Alec Stewart, Martin Crowe and the two Sri Lankans Arjuna Ranatunga and Aravinda de Silva in being cleared.

They were all the subject of allegations by Indian bookmaker MK Gupta that they had taken money for match information.

"Much of the allegations were on one man's say so and natural justice suggests the guys mentioned should not face disciplinary action unless Gupta was prepared to support his evidence," said Condon.
