PARIS, June 18 (Xinhua) -- Belgian cycling star Tom Boonen has been banned from competing in the Tour de France following his positive drug test for cocaine, organizers ASO (Amaury Sport Organization) announced on Thursday.

The 28-year-old tested positive for cocaine in April, less than a year after he first tested positive for the drug in May 2008.

However, there was some good news for Boonen as the sport's governing body the International Cycling Union (UCI) announced they would be taking no disciplinary action against him for the positive cocaine test.

"Finally, the UCI Management Committee has decided not to institute disciplinary proceedings against Mr Tom Boonen for having allegedly taken cocaine out of competition," read a statement from the UCI.

Boonen's team have backed him and previously promised to provide legal support if he was refused entry to the Tour.

Quick Step manager Patrick Lefevere had threatened to demand millions of euros in compensation if his rider was excluded.
