He was regarded as one of the greatest racehorses on Earth, known for his strength, speed, and good nature - but Shergar's fate will perhaps always remain a mystery.
Foaled in 1978, the thoroughbred bay colt racehorse became a household name after winning the Epsom Derby in June 1981 by a colossal 10 lengths, the longest margin in racing history ever recorded by an unknown rookie.
This victory was quickly followed by impressive wins at both the Irish Sweeps Derby and the King George VI and Queen Elizabeth Stakes, with Shergar outrunning his competition by four lengths each time.
