Norwegian Olympic gold medalists Marius Lindvik and Johann André Forfang are accused of adding extra material to the crotch of their ski suits, potentially allowing them to travel further in air.

Team officials are accused of altering athletes' suits to enhance their aerodynamics. The suspension by International Ski and Snowboard Federation (IFS) follows last week's FIS Nordic World Ski Championships.

Cheating by Norway team officials manipulating ski suits has shaken a national reputation for fair play and high-minded principles at their home Nordic world championships.
