I saw this earlier. I believe the young person responsible was an environmentalist of some description. The story I read didn't suggest he was trans, he appears to have presented himself as a female with a disability to attract less attention as a possible security threat.
It's almost as if even men know which sex presents the greater danger to others and are happy to use that to their advantage when it suits them.
No one would ever do that and besides safeguarding is so old fashioned!
