The anti-doping program for the Paris Olympics caught five athletes after earlier finding 40 rule violations among competitors who had been expected to take part in the Games, the agency that ran the operation said Thursday.

Around a third of Olympic athletes were drug-tested during the Paris Games this year, with only five positive results, according to the International Testing Agency.
