The Italian Olympic Committee (CONI) performed unannounced doping tests of riders in the Tour de France, including the new yellow jersey holder, Frank Schleck. CONI made a pre-race agreement with the Tour organisers, Amaury Sport Organisation, to perform the doping controls at the finish of stage 15, which ended inside Italy at the ski resort of Prato Nevoso.
Riders were housed in nearby Cuneo, the start of Tueday's stage, for the Tour's second rest day. As the riders were still in Italy, CONI tested as many as six riders.
The riders' samples will be sent to Rome for testing, and should any test positive for banned substances, the rider could be prosecuted under Italy's doping laws.
