A female trainer who has made allegations of sexual harassment and bullying will be contacted by the British Horseracing Authority.
Gay Kelleway told the Daily Mirror she was pinned against the wall by a fellow jockey in the presence of horse racing officials.
The 53-year-old also alleged that she was continually harassed during her time as a jockey and as a trainer.
A BHA statement said it is taking the allegations "extremely seriously".
It added: "We are working with all partners in our sport to ensure people are treated with respect. We are contacting the trainer concerned to seek further details."
Kelleway became the first female jockey to win a race at Royal Ascot when she claimed victory on Sprowston Boy in 1987.
She told the Mirror: "What I went through would be enough to push someone, especially fragile girls, to suicide."
Who is Gay Kelleway?
