Officials at the Professional Jockeys Association have stressed they are keen to see all relevant documentation relating to claims made in the Indian media over riders Martin Dwyer and Paul Mulrennan.
Reports in the Mumbai Mirror suggest the jockeys will be asked to return to the sub-continent by Royal Western India Turf Club stewards to answer serious allegations arising from what is claimed to be a taped recording of the jockeys dating to February 13, 2010 and regarding the Eclipse Stakes run the following day at Mahalaxmi racecourse.
Both jockeys vehemently deny any wrong-doing.
Dwyer has recently brought to an end a long-running saga from a race at the same racecourse earlier this year, which at one stage saw him facing an eight-month ban before successfully asking the British Horseracing Authority not to reciprocate the original 56-day suspension.
Paul Struthers, chief executive of the PJA, said: "Neither Martin nor Paul, nor the PJA, have had any correspondence or contact whatsoever from the Royal Western India Turf Club.
"We are disappointed and concerned that the RWITC seem intent on playing this out through the media and both jockeys forcefully deny any involvement in the serious allegation that has been made against them."
Quoted in the Mumbai Mirror, RWITC chief stipendiary steward Pradyumna Singh said: "The stewards have directed me to send a copy of the CD and its transcript to the BHA for their information.
"I will be seeking legal opinion from the club's advisor and, if approved, will send copies of the CD and its transcript to the BHA and ask them to assist us in delivering the evidence to Dwyer and Mulrennan.
"A show cause notice will also be served on the two jockeys and they will be asked to appear in person before me within three weeks."
