Pakistan's former cricket captain Imran Khan believes the ICC will have to adopt new ways to curb the menace of match-fixing as it is very difficult to detect and prove.
Imran's comments came few days after former Sri Lankan captain Hashan Tillakaratne claimed that match-fixing had been prevalent in Sri Lankan cricket since 1992.
Pakistan's former captain Rashid Latif, who blew the whistle on corruption in cricket in 1994, has also backed Tillakaratne's claims.
Imran said he had no idea whether fixing took place in cricket and it was always going to be difficult to detect such instances.
"I have no clue whether it happens or not," Imran told reporters at the Moin Khan Academy.
"If it happens it's very hard to notice. People can only point it out but it's very difficult to prove. Special measures are required to deal with the menace."
"The ICC should find new ways to control it. There should be a sort of check," he added.
Imran said the Pakistan Cricket Board should have taken action the first time fixing allegations surfaced in Pakistan cricket.
Latif said he was sure Tillakaratne had evidence to back his claims. "I have no doubt he has evidence but it all depends on how things go no. If strikes a deal with Sri Lankan authorities than the matter will be brushed under the carpet as in other instances in the past," Latif told PTI.
