LONDON (AP) — British sprinter Nigel Levine, who has won world and European championship medals, has been banned for four years for doping.
The U.K. Anti-Doping agency says Levine tested positive in an out-of-competition test last year for the banned substance clenbuterol, which can be used to burn fat.
UKAD's ruling says Levine accepted a four-year ban in August after arguing "one of the supplements" he was taking was contaminated.
UKAD says Levine provided two samples of a supplement for testing, but it couldn't test them because one container was empty and the other was from a different batch to the one Levine said he'd taken.
Levine won the 4x400-meter relay at the 2014 European indoor championships, silver in the same event at the 2012 European championships, and relay bronze at the 2013 world championships.
