CAPE TOWN (Reuters) - South African Olympic swimming gold medallist Roland Schoeman says he still has ambition to compete at the Tokyo 2020 Games despite serving a one-year suspension after testing positive for a banned substance.

Governing body FINA said Schoeman tested positive for the prohibited substance GW501516, a hormone and metabolic modulator, at an out-of-competition control on May 18 last year.
