Victorian trainer Richard Laming and two stablehands have been charged for stomach-tubing a horse on race day.

Racing Victoria stewards uncovered the actions during a Melbourne Cup day stable inspection which led to Jamaican Rain's scratching from the Flemington meeting.

Jamaican Rain was favourite for the Jim Beam Stakes on November 5 but was scratched on advice from RV's Compliance Assurance Team that she was lame.

Stewards on Thursday issued two charges against Laming and one each against registered stablehands Marnu Potieter and MD Zeyaur.

Stewards allege Laming, on the morning of the race and before the CAT arrival at the stable, stomach-tubed, caused the stomach-tubing, attempted to stomach-tube and/or was a party to the stomach-tubing or attempted stomach-tubing of Jamaican Rain.

Potgieter faces the same allegations as Laming while Rahman has been charged with being a party to the alleged stomach-tubing or attempted stomach-tubing of the mare.

Laming faces a second charge of obstructing, hindering or delaying the CAT in exercising their powers and performing their functions and duties in that he deleted or incited another person to delete, files from a Network Video Recorder.

All three will face the Victorian Racing Tribunal at a future date.
