Teesside Olympian Richard Kilty has said it was "heartbreaking" to be stripped of his Olympics silver medal alongside his relay team-mates.
Kilty, who is from Stockton-on-Tees, ran a remarkable third leg for the GB team in the 4x100m relay in Tokyo but narrowly lost out to Italy for the coveted gold medal.
But it later emerged that team-mate CJ Ujah tested positive for the prohibited substances ostarine and S-23 after the race, which took place on August 6, 2021.
