Tate was detained alongside his brother Tristan last month as part of an investigation into allegations of human trafficking and rape, which they deny.Earlier, Mr Tate was seen carrying what appeared to be a copy of the Quran as he walked into Bucharest Appeal Court handcuffed to his brother.After the arrests on 29 December, police said they had identified six people who were allegedly "sexually exploited" by what it called an "organised criminal group".Police alleged the victims were "recruited" by the British citizens, who they said misrepresented their intention to enter into a relationship with the victims - which it called "the loverboy method".Born in the US before moving to the UK, Mr Tate, 36, went on to have a successful career as a kickboxer."
