The cases include one coach who was arrested for engaging in sexual communications with a child.

In a separate case, another was arrested for voyeurism at a place of work after placing a camera in female toilets.

Both incidents occurred in 2019.

In a statement, the governing body said it was unable to comment on active investigations.

But British Judo insisted “all allegations such as these are treated extremely seriously and are subject to a risk assessment process which will usually lead to a coach’s suspension from coaching pending police investigation and any prosecution”.

It is understood these cases are not part of a bullying investigation that was revealed by the BBC last month, and which is expected to be published imminently.

However, the review is looking into a physical incident that was reported to the police, also in 2019.

British Judo said that because it is part of the ongoing investigation, it is unable to comment further until the full findings of the investigation are published.

Safeguarding Review revealed

In the 2019 independent safeguarding review of the sport, which is heavily redacted, the review team states it is “concerned that current policies and procedures around safeguarding lack sufficient independence and transparency and that consequently the BJA [British Judo Association] are susceptible to challenge around their decision making and responses to safeguarding concerns”.

Carried out by LimeCulture, a national sexual violence and safeguarding organisation, it also notes that it was “unclear… whether personnel who make up the Area Boards have the requisite skills and knowledge to play and part in delivering safeguarding.

“Key informants told the review team that at area committee level, some members demonstrated an ‘old-fashioned attitude’ towards safeguarding, suggesting that they saw this as someone else’s role and did not recognise their responsibility in addressing safeguarding at their level.”

Elsewhere, the report states that “from the information provided to them, the review team found that, on the whole, decision making at NGB [national governing body] level appears to be based on sound safeguarding principles. However, the review team is of the view that there is often insufficient information recorded to explain why decisions have been made”.

The report reveals that there were 100 safeguarding cases reported to the British Judo Association in 2017, followed by 69 in 2018 and 54 in the first nine months of 2019.

However, according to the review, “key informants told the review team that in their view, given the number of clubs affiliated to the BJA (approximately 800), the number of cases seemed low and they were concerned the BJA does not have a true understanding of the extent of safeguarding concerns within its clubs”.
