Twyford trainer Tim Jarvis and his father, Alan, say they have done nothing wrong, despite the prospect of a new probe by the British Horseracing Authority.
The BHA say they will look into reports that Alan Jarvis joined his son in the unsaddling enclosure after Rogue Wave was runner-up in the one mile handicap at Newcastle on Friday.
Jarvis snr, although no longer deemed a suitable by the BHA person to hold a training licence, is still allowed to attend race meetings.
But because of the family association, Tim Jarvis had to agree to five strict conditions imposed to stop his father having any involvement with the operation at Mill Race Stables, before being granted a licence earlier this month.
Although a suggestion is that his presence in the unsaddling enclosure may breach these conditions, both Jarvises deny there was any wrongdoing.
“My father was there (at Newcastle), but it was nothing to do with me,” said Tim Jarvis.
“I am training the horses and he is not involved.
“I was told I wasn’t to speak to him about any racing matters which I haven’t.”
Alan Jarvis added: “I only went into the paddock to have a quick word with the jockey to see how he got up there. I have a lot of friends involved in the syndicate.
“If an owner gives me tickets and invites me to go racing, it is none of their (the BHA’s) business. They don’t control me, I can go racing when I want.”
BHA spokesman Robin Mounsey said: “We are aware of the reports and will look further into the matter when we have access to the appropriate footage.”
