Two Norwegian ski jumpers and three team officials have been charged following allegations of tampering with ski suits, the sport's governing body has announced.

Olympic medallists Marius Lindvik and Johann Andre Forfang have been charged with equipment manipulation in the men's large hill event at the World Ski Championships in Trondheim, Norway, in March.

Then head coach Magnus Brevik, assistant coach Thomas Lobben and service staff member Adrian Livelten have also been charged following an International Ski Federation (FIS) investigation.

Speaking at the time, FIS general manager Jan-Erik Aalbu said the team had "tried to cheat the system" by putting reinforced thread in the jumpsuits of Lindvik and Forfang.
