A rider for the Queen's horse trainer has been charged with assault after an incident involving a former jockey turned PR director.
John Maxse, former PR director at both the Jockey Club and the British Horseracing Authority, was photographed at the weekend with a black eye and cuts and bruises to his face.
The 45-year-old former jockey, who now works as a communications consultant for Qatar Racing, suffered "serious injuries" and required hospital treatment following the alleged attack in Newmarket.
Jonathan Nolan, who is a work rider for the Queen's trainer Sir Michael Stoute, has been charged with grievous bodily harm with intent, Suffolk Police said.
The incident happened in Corsican Pine Close in the town at 11.30pm on July 21.
Afterwards Mr Maxse joked on Twitter that he looked like film character Rocky Balboa.
A spokeswoman for Suffolk Police confirmed officers had been called to the incident.
Nolan, of Skeaping Close, Newmarket, appeared before Bury St Edmunds Magistrates' Court last week and has been released on bail to a later date.
The 32-year-old, who works at Sir Michael's Freemason Lodge Stables in Newmarket, used to ride the Queen's horse Carlton House when it was trained there.
A work rider's normal duties would include mucking out, exercising, grooming and feeding the horses.
