Amusan lined up in the final as favourite for gold and she blazed to a new games record of twelve point three zero seconds to retain the title she won 4 years ago in the Gold Coast, Australia.
Devynne Charlton finished a distant second to win silver for the Bahamas while Cindy Sember whose father is Nigerian, won bronze for Great Britain.
Despite winning the race comfortably, Amusan said she did not execute the race to the best of her ability.
She dedicated her latest gold medal to God, her support system which includes her family, supporters, and her Jamaican coach, Lacena Golding Clarke under whom she has been training since 2016.
