A Romanian court is due to rule on a challenge filed by Andrew Tate, an internet personality notorious for hate speech, against his 30-day arrest for alleged human trafficking and formation of an organised crime group to exploit six women.
Tate, his brother Tristan and two Romanian female suspects were detained by Romanian anti-organised crime prosecutors on December 29 pending a criminal investigation.
They have denied wrongdoing through a lawyer and have challenged the arrest warrant.
Prosecutors have said the Tate brothers recruited their victims by seducing them and falsely claiming to want a relationship.
The victims were then taken to properties on the outskirts of Bucharest and through physical violence and mental intimidation were sexually exploited by being forced to produce pornographic content for social media sites which generated large financial gains, according to prosecutors.
Prosecutors also said one of the brothers raped one of the victims in March of last year, which is when the investigation started.
"The possibility that the suspects would evade investigation, leave Romania and settle in countries that do not allow extradition given their financial possibilities and public comments to that regard cannot be ignored," the court judge said in the written record approving the arrest.
Prosecutors have seized 15 luxury vehicles and more than 10 properties and homes belonging to the suspects in Bucharest and Prahova and Brasov counties, Ramona Bolla, a spokesperson for Romanian anti-organised crime unit DIICOT, told Reuters.
The seizure was meant to prevent the assets from being sold or concealed.
Should the court uphold the arrest warrant and the investigation need more time, prosecutors can seek approval for further extensions of up to 180 days of detention under Romanian law.
Tate gained mainstream notoriety for misogynistic remarks and hate speech, which got him banned from all major social media platforms, although his Twitter account was reinstated in November.
The former professional kickboxer, who holds US and British nationality, has said women are partially responsible for being raped and that they belong to men.
He is a self-professed misogynist.
On a podcast last year, he said he started making money by convincing multiple girlfriends to video chat and share the profits back when he lived in London.
"How can I use these women to make me money?" Tate said, adding his business started with two girlfriends and peaked with 75 women working for him and earning $US600,000 ($A867,573) a month.
He has also said he moved to Romania after being investigated in the UK on charges of sexual assault, which were ultimately dropped because he liked living in countries where corruption was accessible to everybody.
