ParalympicsGB's SM8 individual medley gold medal winner Oliver Hynd has revealed his disbelief after adding gold to the silver and bronze he had already won.

Hynd powered away from the field after the final turn to take the top prize by nearly two seconds and the 17-year-old reflected on his "amazing" achievement.

"I can't believe it, it was amazing," Hynd said. "I've had to work a lot on my breaststroke and I held my own in a really strong breaststroke field.

"At first I thought it can't be right [that I won] but I'm over the moon.

"I had times I wanted to hit and whatever medals came with that I'd take but this is just amazing."

Oliver's brother Sam just missed out on a medal as he finished fourth in the final.
