Heard that there were some legal issues related to his stable. His syces hit a few horses causing an injury. After which most of the owners withdrew their horses from stables. And there was a police complaint about it. This is what I have heard. Please correct me if I am wrong or if there is any other reason. 

H.J.Antia stopped training after five racehorses in his Pune stables were deliberately attacked and injured by staff members suspected of foul play. Following the incident and police investigation, owners withdrew their horses over safety concerns, effectively shutting down his stable operations.
