LONDON (AP) — Godolphin trainer Mahmood Al Zarooni is to attend a British Horse Racing Authority disciplinary inquiry after prohibited substances were found in samples taken from 11 horses at his stables in Newmarket, England.
Godolphin racing manager Simon Crisford says "this is a dark day for Godolphin. We are all shocked by what has happened."
Godolphin confirmed late Monday on its corporate website, godolphin.com, that Al Zarooni had admitted making a "catastrophic error."
Al Zarooni has trained some high-profile winners, including Monterosso in the 2012 Dubai World Cup — the world's richest horse race — since joining the racing organization of Dubai ruler Sheikh Mohammed bin Rashid al Maktoum.
All horses which returned positive tests will be barred from racing at least until the BHA inquiry is finished.
