World 1500m champion fails drugs test

The 25-year-old Ethiopia-born Swede failed an out-of-competition test conducted by governing body the IAAF.

Aregawi, who won gold at the 2013 World Championships in Moscow and 2014 World Indoor Championships in Sopot, has requested a B sample be tested.

Britain's Hannah England finished fourth behind Aregawi in Moscow.

There is no suggestion Aregawi's performance in that race is under scrutiny.
