Leading Australian trainer Darren Weir was arrested during a raid on his stables on Wednesday, according to media reports.
Weir is one of the country’s most successful handlers and sent out the 2015 Melbourne Cup winner Prince of Penzance, who was famously partnered by Michelle Payne to become the first woman to win the coveted prize.
Police said three men were arrested following raids on properties in the Warrnambool and Ballarat areas in Victoria and all were released without charge later on Wednesday.
At a press conference, Victoria Police assistant commissioner Neil Paterson confirmed four ‘jiggers’, which are taser-like devices, an unregistered gun and a substance believed to be cocaine had been seized.
Racing Victoria’s integrity services chief Jamie Stier explained the raids were related to an investigation by his team.
A statement read: “Racing Victoria’s Integrity Services team has been conducting an investigation into the activities of licensed persons in the Warrnambool and Ballarat areas.
“During the course of our investigation we sought the support of Victoria Police’s Sporting Integrity Intelligence Unit on the matter, instigating their investigation.
“The Sporting Integrity Intelligence Unit this morning executed warrants at properties in Warrnambool and Ballarat where they arrested three licensed persons for questioning. Members of the Racing Victoria Integrity Services team attended licensed stables to assist Victoria Police and to investigate potential offences against the Rules of Racing.
“As the matters are the subject of on-going investigations by Victoria Police and Racing Victoria, we are not at liberty at this time to disclose the identities of the persons arrested nor the details of the investigations.
“Racing Victoria is committed to maintaining the highest integrity standards in our sport and, where appropriate, we will continue to work with Victoria Police on those investigations.”
