A 14-month investigation by United Kingdom Anti-Doping into allegations of wrongdoing at British Cycling and Team Sky has ended with no charges being brought against either organisation due to a "lack of contemporaneous evidence". An inquiry was launched in September 2016 after British newspaper the Daily Mail reported a mystery package had been delivered to Richard Freeman, the doctor of now retired Tour de France winner Bradley Wiggins, then a Sky rider.
The package, reportedly delivered at the end of the 2011 Criterium du Dauphine race in France, was alleged to have contained a banned corticosteroid, but Freeman insisted it was the decongestant fluimucil, a legal substance. United Kingdom Anti-Doping (UKAD) said that despite conducting interviews with 37 current and former staff at both British Cycling and Team Sky, it had been unable to prove or disprove Freeman's claims. UKAD said the investigation would now be closed unless new evidence came to light.
