Colombian 400 metre runner Diego Palomeque has been provisionally suspended by the International Olympic Committee (IOC) after failing a drugs test.

The 18-year-old was due to run in the 400m heats today but was withdrawn following his suspension.

The IOC have also confirmed Russian track cyclist Victoria Baranova's expulsion from London 2012.

The 22-year-old tested positive for testosterone in a sample taken on July 24 in Belarus and her departure from the Games was first confirmed by cycling's world governing body, the UCI.
