Fallon, who denies any wrongdoing, was arrested and bailed in September 2004. Last night, he left the police station just after 7.15pm. The 40-year-old has previously said he had been questioned about his involvement with Miles Rodgers, formerly a director of the Platinum Racing Club syndicate.
A total of 27 people have been arrested, including fellow riders Robert Winston, Darren Williams, Fergal Lynch and Paul Bradley, along with trainers Karl Burke and Alan Berry. They all deny any wrongdoing.
Twenty people are due to answer bail over the next month. Five others have had their bail extended.
John Blake, the chief executive of the Jockeys' Association, said: "I'm extremely disappointed, as I'm sure Kieren is, that the matter continues to drag on. Given the investigation requires more time, one would have to ask how much further on they are in what seems to be a very thorough investigation. But I would underline that no-one has been charged."Reuse content
