"Spot-fixing is rife in the game. And I'm talking globally. It's a Pandora's Box. It's staring you straight in the face, but difficult to prove. Almost impossible to prove," he is quoted as saying in the book, according to a release by the publishing house's PR agency.
"I think it (IPL) was clean, but I could never, sitting here today, categorically tell you that we picked up everything for spot-fixing, and that goes for all games, not just IPL," says Modi.
"It's extremely difficult to spot. We had to warn players from time to time. We found undesirable elements in the stadium and removed them. We found them touring with players or managers of players who were in touch with bookmakers and we removed them."
When contacted, Modi told HT he hadn't read the book and didn't know in what context his comments had been used.
"Ed Hawkins has been investigating fixing for years and years, everywhere, and we have been in conversation over the years on many issues. I haven't read the book, so I can't comment till I have seen in what context he's quoted me."
