Brian Hamilton-trained Chief Oscar died after winning the Toals Ulster Grand National at Downpatrick on Wednesday.

The horse, ridden by Andrew Lynch, had just held off the challenge of Bally Wall to win, with Selection Box third.

Nine-year-old Chief Oscar collapsed after passing the finish post to secure the 16,000 first prize.

Blank Hand set the pace but the chasing pack closed up and Chief Oscar (16-1), owned by Robert Donaldson, eventually won by a neck after some fine jumping.

Hamilton said: "He collapsed past the line, the vet said he probably ruptured an artery and had a heart attack.

"He's just such an honest horse and he gave his all. He has won three times around here, it's just such a horrible thing to happen."
