Criminal charges against former Deagon trainer Brad Smith have been dropped.

Smith faced three charges involving an alleged fraud in a horse sale.

A Queensland Racing Integrity Commission spokesman the charges against Smith had recently been dropped.

"The Racing Crime Squad has confirmed the charges have all been discontinued," the spokesman said.

"However, at this stage Smith still faces a hearing about some alleged racing industry offences."

Smith was suspended from training but is currently on a stay from the appeal body at the Queensland Civil and Administration Tribunal.

His case is expected to be heard soon.

Smith, regarded as one of the most promising young trainers in Queensland, has not had a runner in six months while he fights the charges.
