Read earlier they tested positive for XY chromosomes and failed gender tests in the past, there's another set to fight in a similar boat too. Eye test also says to me that almost certainly ain't a woman. The Italian boxer quitting that early after the first punch probably also hints towards something she knows too.
There's also the comments from the IOC bloke:
"I would just say that everyone competing in the women's category is complying with the competition eligibility rules."
"They are women in their passports and it is stated that is the case."
He added it would be "invidious and unfair" to discuss details of individual athletes.

Dunno about anyone else but that just sounds like tiptoeing about. Surely you could just say "she was born a woman" and then Bob's your uncle and everything is put to rest, except it seems in this case, I'm pretty positive Bob's your aunt.
