Cocaine traces have been found at the European Parliament in an inquiry by one of Germany's main broadcasters.
The Sat-1 channel sent reporters to take 46 swabs from toilets and other public areas of the Brussels buildings. Nearly all tested positive for cocaine.
A European Parliament spokeswoman said cocaine abuse was not a problem among staff working at the buildings.
A professor who analysed the samples said the amounts found were too great to have been carried in on clothing.
