Swimmer Kristian Gkolomeev of Greece has beaten a world record at the controversial Enhanced Games in Las Vegas.
The 32-year-old clocked 20.81 seconds in the men’s 50m freestyle – but his time will not be recognised by official authorities.
The results are considered illegal by global sporting bodies because athletes can take banned performance-enhancing drugs.
