LONDON -- Former European champion Nigel Levine of Britain has been banned from competition for failing a drugs test, the UK Anti-Doping announced on Tuesday.

Levine, who won a European outdoor relay gold in 2014 and an indoor relay gold in 2013, has been banned from all sport for four years.

It was revealed that the 29-year-old, who competed at the 2016 Rio Olympics in the 4x400m relay event, tested positive for banned asthma drug clenbuterol following an out-of-competition test on Nov 24, 2017.

Clenbuterol is on the World Anti-Doping Agency's prohibited list because it is deemed a performance-enhancing drug and can induce weight loss.
