"UK Sport can confirm that it has commissioned an independent investigation into allegations made at the BBSA," a spokesperson said.

"While the process is ongoing, we are unable to comment any further."

The investigation is allegedly related to a complaint made in July by BBSA Board member Colin Rattigan.

Rattigan claims that he was subject to an "extended period" of bullying and harassment, and that recordings of Board meetings were made in an attempt to entrap him. 

It is reported that he also raised this as a breach of privacy issue with the Equality and Human Rights Commission and the Information Commissioner's Office.

In addition, Rattigan claimed a a number of sources had told him that bobsleigh pilot Lamin Deen and other black coaches were being subjected to discriminatory treatment.

"The Board welcomes UK Sport's independent investigation and are happy to cooperate fully," the BBSA said in a statement. 

The BBSA has already been the subject of an independent investigation by UK Sport, with the organisation looking into allegations of a "toxic culture" in 2017.

Its bobsleigh funding was axed and the governing body was told by UK Sport that its £7.2 million ($9.3 million/€7.9million) investment in its successful skeleton programme was contingent on a major shake-up of the BBSA Board. 

Half of the eight-strong BBSA Board stepped down after the Pyeongchang 2018 Winter Olympic Games.

The current Board has an equal split of male and female representatives and includes double Olympic skeleton champion Lizzy Yarnold.
