The bank details of jockey Fergal Lynch were found at the home of professional gambler Miles Rodgers, the Old Bailey race fixing trial was told today.
They were found in a black briefcase in Rodgers' hallway at White Gates, in Sheffield, on the morning he was arrested in September, 2004, according to uncontested evidence.
Statements read from City of London police said mobile telephones were also seized in the early-morning raid.
Officers also searched Rodgers' Italian restaurant, Tiamo, in Sheffield and found paper in a shredder.
Some of it was able to be re-constituted by Police Sergeant Richard Peacock, who colour-coded strips and photo-copied them, the court heard.
One of the pages had the initials KF and £2,500 (€3,596) on it, he said.
Earlier, Andrew Balding, the trainer of Ballinger Ridge, agreed to a defence suggestion Kieren Fallon made a "howling blunder" on the horse and was "mortified" after they lost at Lingfield on March 2, 2004.
Fallon had a commanding lead but eased up and finished second in the betdirect.co.uk Median Auction Maiden Stakes, in which he was beaten a short head by Rye.
Mr Balding said later Fallon had been worried that the mandatory 21-day ban for "dropping his hands" would mean him missing one of the world's richest races, the Dubai World Cup.
Missing the event meant Fallon had to suffer "a huge penalty" for his failure, said Balding.
Fallon (aged 42), Lynch (aged 29) and Darren Williams (aged 29) deny the conspiracy between December 2002 and August 2004 to allow horses to lose so a betting syndicate could win money.
Lynch's brother, Shaun Lynch (aged 38) professional gambler Rodgers (aged 38) and Philip Sherkle also plead not guilty.
Rodgers also denies concealing the proceeds of crime. All the defendants are on bail.
The hearing was adjourned to Monday.
