World indoor 1500m champion Abeba Aregawi is "shocked and devastated" after a failed drugs test, says her agent.

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.

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

"She is saying I don’t know anything about this medication," said her agent Valentijn Trouw.
