Victorian stipendiary stewards ordered the withdrawal of one of transtasman trainer Mike Moroney's runners at the Flemington meeting after a race morning stable inspection. 
Birak Attack was scratched from the last race at Flemington on Wednesday after two stewards reported the horse had been treated with a vitamin-enriched paste called
         Cophos B. 
A stablehand gave evidence that she thought the horse, an emergency for the race, had not gained a start and set about treating it. 
The evidence was corroborated by Moroney and his stable foreman, The Australian newspaper reported. 
Cophos B is not a prohibited substance, but treatment of horses on race day is a breach of the rules. Stewards will reconvene their inquiry when test results from a sample of the paste and a swab sample from Birak Attack are back from analysts.
