Racing put on notice after doping charges NSW authorities are keen to stamp out doping in horse, harness and greyhound racing after two men were charged with twice giving a winning horse a performance-enhancing substance. Prussian Secret won the Tamworth Cup and a purse of $40,000 last month, but detectives from the firearms and organised crime squad were tipped off that the thoroughbred had been "drenched" hours before the race. On Sunday, detectives intercepted the horse a few hours before it was to run in the Gunnedah Cup. It was tested for the same substance and scratched from the race. The horse's 27-year-old trainer and co-owner, and a 47-year-old man were charged with facilitating and engaging in conduct that corrupts the betting outcome of an event. The trainer was also charged with betting offences. "We will allege that bets were made by those people or on their behalf in relation to the running of the Tamworth Cup," Detective Superintendent Ken Finch told reporters in Sydney on Monday. The men are the first two people charged by Strike Force Trentbridge, which began early this year with the aim of stamping out animal doping. "Our investigation will be ongoing in relation to not only that horse but across the board," he said. Drenching involves administering bicarbonate to the horse before a race to counteract the build-up of lactic acid, allowing it to compete longer and improve its performance. It remains a legal practice but is prohibited 24 hours prior to a race. Both men were granted conditional bail to appear in Tamworth Local Court on May 27. Police will continue to investigate if anyone else knew if Prussian Secret was allegedly doped before the Tamworth Cup and placed bets on that assumption. The eight-year-old horse has won 15 races in 41 starts, netting a total of $290,000 in prize money since 2008. Prussian Secret is trained at Tamworth and has mainly competed in country races but also won in Brisbane in 2010.
