With the 2016 Rio Olympic Games just around the corner, some past misbehavior has caught up with some of the athletes hoping to win medals later this year. The International Olympic Committee announced there are 31 more athletes in trouble for doping. This time, back in the 2008 Beijing Games.

FOX's Simon Owen reports from the European Bureau:

The International Olympic Committee revealing that 31 athletes expected to compete in Rio are now facing bans for doping. The IOC has been re-testing samples from the 2008 Games in Beijing, using updated techniques.

The athletes involved haven't been identified yet, but officials say they come from 12 different countries and compete in six sports. Olympic officials says further test results will follow with a focus on the 2012 Olympics in London and they're re-examining the anti-doping setup at the 2014 Winter Olympics in Sochi, Russia, after allegations Russian officials tampered with results.
