Disqualified trainer Darren Weir has been charged by police with defrauding racing officials and animal cruelty, after jiggers were seized during January property raids.
Detectives from the Sporting Integrity Intelligence Unit charged four men on Wednesday.
The 49-year-old Weir, who now lives in Baringhup near Maldon, has been charged with nine offences.
Charges against the former trainer include conspiracy to defraud Racing Victoria stewards, three counts of engaging in torturing, abusing, overworking a thoroughbred race horse, three counts of causing unreasonable pain or suffering to a race horse, possessing an unregistered fire arm and using a controlled weapon without excuse.
A 38-year-old Yangery man has been charged with 16 offences, including conspiracy, two counts of engaging in conduct that corrupts or would corrupt a betting outcome and animal cruelty.
A 27-year-old Warrnambool man has been charged with seven offences, including cruelty to animals and conspiracy to defraud racing stewards. A 31-year-old Warrnambool man has been charged with one count of using corrupt conduct information.
A police media spokeswoman said the charges were "part of an investigation into alleged illegal activity within the thoroughbred racing industry".
The charges have emerged from warrants executed at properties in Miners Rest and Warrnambool on January 30 this year.
A number of items, according to the media spokeswoman, including a firearm and what is believed to be conducted energy devices (jiggers) were seized from the properties.
All four men will appear at Melbourne Magistrates Court on October 23.
In a short statement, Racing Victoria confirmed it had been advised of the police charges.
"RV Stewards are giving these matters careful consideration and will provide a further update in due course," it said.
Weir's properties were sensationally raided by police in January and the findings led to the champion trainer being disqualified from racing for four years.
He was found guilty on charges of possessing electronic equipment ("jiggers") that could be used on horses and of conduct prejudicial to the image of racing.
It was a shattering blow for Weir and for the community in Miners Rest, where he had employed a large number of people.
After the ban was handed down, Weir's stables in Miners Rest were purchased by the training partnership of Ciaron Maher and David Eustace, which continue to race out of the premises.
Weir famously won the 2015 Melbourne Cup with Prince of Penzance, which was ridden by Michelle Payne. The triumph is part of a feature movie titled Ride Like A Girl.
He is a multiple Victorian metropolitan premiership winner, has claimed 36 group 1 races and holds the Australian record for most amount of winners in a single season.
Anyone with information about illegal activity is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report to crimestoppersvic.com.au.
