Things are heating up for Jamaicas women bobsledders at the Winter Olympics in Pyeongchang, South Korea.

The teams German coach, former Olympic champion Sandra Kiriasis, has quit, just days before athletes Carrie Russell and Jazmine Fenlator-Victorian were due to compete in the womens bobsleigh event.

Kiriasis is now threatening to take the teams bobsled that she rented for the games, reports the BBC. The sled threat may jeopardize Russell and Fenlator-Victorians shot at becoming the Caribbean islands first Olympic female bobsledders.

Kiriasis resigned Wednesday after the Jamaica Bobsleigh and Skeleton Federation told her out of the blue that it had changed her position from driver coach to track and performance analyst, she wrote on Facebook .

(I) would have to leave the Olympic village, would lose my accreditation as part of the Jamaican team and was not supposed to have any more contact with the athletes, she said.

Kiriasis, 43, said shed supported the team far beyond the call of duty at all times by securing sponsorship, equipment and the rented bobsled but she could not accept to be treated the way I have been treated.
