FIRS and the CIC have confirmed that skaters Angie Perez (Colombia), Nicolas Bermudez (Colombia), and Paola Serrano have tested positive at the anti doping tests carried out in 2010 at the World Roller Speed Skating Championships.

Those athletes, who have been disqualified by the Colombian Federation, have lost their World Championship titles. The CIC will award medals according to new rankings that exclude the skaters who tested positive.
