Richard Kilty: British sprinter wants to win "clean" at Rio Olympics

British sprinter Richard Kilty tells BBC Look North he is determined to "shine a light on the sport" along with other "clean" athletes at the forthcoming 2016 Rio Olympic games.

Kilty expressed his concerns about doping at the games, and has urged the International Association of Athletics Federations and World Anti-Doping Association to come down hard on those that are caught at the games.
