Sprinter Richard Kilty was left furious after he finished last in the 100 metres at the Anniversary Games in London on Sunday.
The 24-year-old was not angry at his own performance, though, but with the officials after he claims the starting gun failed to make a sound when the runners were in their blocks.
Kilty pulled up believing it would be called a false-start, before realising the race was continuing. The world indoor champion couldn't make up the time lost, though, leaving Harry Aikines-Aryeetey to take victory in 10.29 seconds.
The athlete took to Twitter to vent his frustrations, calling the incident an "absolute disgrace."
"How can they not fire a gun, then I stop running, others keep running, Poor officials here. Should have been called back."
Elsewhere, 110m hurdler William Sharman impressed as he narrowly missed out on first place.
Sharman, 29, finished in 13.29 seconds - the same time awarded to first and second place, American Ryan Wilson claiming the photo-finish win.
Positive British performances
There were British wins for Tiffany Porter and Chris Tomlinson, however. Porter won the women's high-hurdles, while Tomlinson leapt to 7.94m to win the long jump.
Both will be hoping to take this form into the Commonwealth Games which begin this week.
