The Norwegian coaches Patrick Oberegger and Siegfried Mazet witnessed the situation that stirred up emotions before the start. During the women's shoot-in, a man suddenly appeared on the mountain behind the target boards while several riders lay and fired shots at their mats.

According to Norwegian NRK, it was a security guard who managed to walk behind the target boards during the ladies' push ahead of the distance yesterday.

- This is not good. It's very dangerous. There are security rules on the site that say no one should be in the area in the meantime, Mazet tells NRK.

Norksan Ingrid Landmark Tandrevold was one of those who noticed it.

- I would shoot when that happens. It takes a lot before we push so much over the boards, but with is something that should not happen. It is pretty clear that one must not be there, she says.

The biathlon uses caliber 22, a bullet that can kill a person.
