Following the BBC Panorama programme "Catch Me If You Can", UKAD Chief Executive Nicole Sapstead said:
"The news tonight reflects the challenge we face to ensure athletes and sports events in the UK are protected from doping.
"Exposing doping athletes and their support network is a responsibility that rests with everyone involved in sport.
"We encourage anybody with information about doping in sport to contact us as it is essential to UKAD’s investigations.
"Our deterrence and detection programme thrives on intelligence and we are firmly committed to taking every opportunity to expose serious dopers and those who drive doping decisions."
