The three Pakistani cricketers embroiled in corruption claims were questioned by London police on Friday.
The police probe came a day after the International Cricket Council charged Mohammad Amir, Mohammad Asif and Salman Butt under its Anti-Corruption Code. The players were charged with various offences relating to alleged irregular behaviour during last week's Test against England at Lord's.
ICC chief Haroon Lorgat has warned the players may face life bans if they are found guilty.
"We are guided by our own code," Lorgat told Sky Sports News. "We have promised prompt and decisive action."
"I don't want to prejudge any outcome. I think these players have been charged, they have still got to be proven as being guilty."
"But it is clear that our sanctions do provide for up to a life ban," he said.
Sir Ronnie Flanagan, the head of the ICC anti-corruption unit investigating the allegations, doesn't believe the incident will permanently scare the reputation of the game.
"It's desperately disappointing that this should happen," Flanagan said, also speaking to Sky Sports News.
"But if there is a cloud that appears to be hanging over cricket at the moment, I think it's temporarily hanging over cricket, I don't think it's a widespread problem."
Butt and Asif will also be questioned by Scotland Yard detectives throughout Friday.
Pakistan's High Commissioner in London, Wajid Shamsul Hasan, believes the ICC is mistaken in charging the players while the police investigation was on-going.
"The ICC has done the wrong thing because when there is a live police inquiry this takes precedence," Hasan told the BBC.
"The ICC made a mistake. It gave assurances nothing would be done until Scotland Yard had completed its investigation."
"To take action now is of course unhelpful, premature and unnecessary considering the players had already voluntarily withdrawn from playing."
