Russian athlete fails test

Shot champ stripped of gold

A Russian 400m runner has been thrown out of the Olympics after failing a drugs test.

Anton Galkin is the 18th athlete to be expelled from the Games for alleged doping offences - a new record.

Galkin tested positive for stanozolol after finishing fourth in his semi-final last Saturday.

The 25-year-old had been planning to compete in the 4 x 400m relay before failing his drugs test.
