One of two people interviewed on Monday in connection with the long-running investigation by the City of London Police into allegations of race-fixing is still in custody.
A spokesperson for the police said: “The person who returned on bail yesterday was questioned throughout the day and has been placed on bail until early March 2006.
“One of the two from Monday has also been placed on bail until March 2006 and the other person from Monday is still in custody, and a warrant of further detention has been served.
“Two people answered bail today and are still being interviewed.”
Kieren Fallon, who was arrested on September 1 last year, spent much of Tuesday being interviewed by police and was later released on bail.
His solicitor, Christopher Stewart-Moore said: “His bail has been put back until March 2006.
“He is looking forward to the inquiry being concluded, hopefully before then, and fully expects that when the inquiry is concluded his name will be cleared.”
In addition to Fallon, individuals apprehended included fellow jockeys 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.
Jockey Gyles Parkin has said the case against him has been dropped. Another person has also been released without charge.
During the investigation, more than 130 police officers raided 19 addresses across Suffolk, North Yorkshire, South Yorkshire and Hertfordshire.
The inquiry is examining allegations involving more than 80 races between 2002 and 2004.
