Australia all-rounder Shane Watson and wicketkeeper Brad Haddin have confirmed they had both been approached by an Indian bookmaker in the past 16 months.
Watson was targeted during last year's Ashes tour of England while a similar approach was made to Haddin during this year's World Twenty20 in the West Indies.
"It was an Indian fan, or that's what I thought it was, who knew a lot about me and what I did in the IPL and was only too kind with his praise about how I've been playing and he enjoyed the way I played," Watson recalled.
"It happened a couple of times when we were at the Royal Kensington Garden in London and I just went through the right channels and (told team manager) Steve Bernard.
"The first time was in the breakfast room talking about cricket really in general and then it got to 'I'd like to take you out for a few drinks' and that sort of thing ... and then the second time it wasn't so much about the cricket side of things, it was more about taking us out and wanting to have some fun in London.
"I didn't think too much more of it until I found out a bit more information and that he was actually one of the illegal bookmakers that were trying to get involved."
Haddin added of his experience: "Basically I was just sitting in my room and I got a knock on my door from someone asking if I wanted to come across to their room to have a drink, which I thought was a bit odd.
"I quickly rang Steve Bernard and John Rhodes (who manages the ICC's Anti-Corruption and Security unit in Australia and New Zealand) just to tell them something weird had just happened.
"I think they checked footage of who the person was and it was someone that they were well aware of. I'd never seen the person (before) or never heard from him or seen him since."
