The International Paralympic Committee (IPC) has revealed that it may take disciplinary action against Heather Mills.
The 45-year-old has been accused of verbally abusing and physically harassing IPC skiing committee head Sylvana Mestre after being told that the new prosthetic leg she was competing on had not been ratified.
"I was trying to explain to [Mills] that this is not the equipment we approved earlier in the year and then that was it, she exploded," Mestre told BBC Sport.
"She jumped on me. She grabbed me from the back and she started to say that 'you don't know who I am, I will make your life miserable'."
IPC spokesperson Craig Spence added: "It was harassment. It was absolutely disgraceful behaviour [by Mills]."
However, Mills has denied that she did anything wrong during her conversation with Mestre.
"Heather waited patiently (as IPC confirmed) to try and explain to Sylvana Mestre that her left boot was legal and purely cosmetic to abide by the archaic IPC rules," a representative of the Englishwoman said.
"Sylvana shouted at Heather, would not let Tony [the GB coach] speak or explain, and stormed back to the boardroom raised table."
Mills, who had the lower half of her left leg amputated following a collision with a police motorbike in 1993, joined the British Disability Skiing team in 2010.
