A man has been charged over his alleged involvement in suspected thoroughbred horse doping in Queensland.
The state police force's Racing Crime Squad charged the 25-year-old Toowoomba man with aggravated fraud, alleging he bought and administered supplements.
His arrest is part of an ongoing probe into the administration of unregulated performance enhancing supplements designed to avoid detection by racing officials.
The man is expected to appear in the Toowoomba Magistrates Court on December 2.
A police operation into suspected horse doping has been running for more than a year, with three men charged with fraud in June.
Police alleged then that the men had dishonestly benefited financially from thoroughbred race winnings.
