(Reuters) - The World Anti-Doping Agency (WADA) is investigating UK Anti-Doping (UKAD) for allowing British Cycling to conduct its own probe after a sample provided by one of its riders contained traces of a banned anabolic steroid, British media reported.

A British rider's sample from an out-of-competition test in late 2010 was reported to have contained irregular levels of nandrolone.
