A man accused of assaulting trainer Wayne Hawkes during trackwork at Flemington last week has failed to appear at an inquiry into the alleged incident.

Jeffrey Walker, a registered stablehand formerly employed by the Hawkes Racing stable, had been called by stewards to attend their inquiry.

After waiting more than 30 minutes beyond the scheduled starting time of the inquiry, a Racing Victoria detective went to Walker's address and spoke to him.

He later told the inquiry Walker said he did not intend to appear and gave no reason why.

Police attending the inquiry later went to Walker's address.

Walker is alleged to have assaulted his former employee in the early hours of July 10 in an incident witnessed by at least three other employees of the trainer.

All three, and Hawkes, provided statements to police on the day of the alleged incident which were tendered to Friday's stewards' inquiry.

Hawkes told the stewards he had been informed by other racing figures at Flemington that Walker had previously acted in an aggressive manner towards them.

No other evidence was given and the contents of the statements were not revealed.

Chief steward Terry Bailey adjourned the inquiry to a date to be fixed.
