The director of a reality show in which a Brazilian student sold her virginity on the internet could be charged with sex trafficking crimes.
Catarina Migliorini, 20, is set to earn £487000 from the controversial sale.
The physical education student was taking part in a documentary by Australian filmmaker Justin Sisely entitled Virgins Wanted.
The winning bidder was identified as a Japanese man named only as "Natsu".
The pair will reportedly consummate the act on board a plane between Australia and the US in a bid to avoid prostitution laws.
But, on Sunday, Brazil's attorney-general, Joao Pedro de Saboia Bandeira de Mello, ordered an "urgent" investigation into the virgin auction, claiming it amounted to "people trafficking". He called on authorities in Australia, where Migliorini lives, to deport her back to Brazil and revoke her visa for "the exercise of prostitution".
