Social media personality Andrew Tate and his brother are suing a Florida woman, saying she falsely accused them of imprisoning her in Romania, leading to their arrest there on human trafficking charges.

The widely followed former professional kickboxer and his brother, Tristan, are seeking at least five million dollars (£3.8 million) in the lawsuit, which was filed in Palm Beach County against the woman, her parents, another woman who lived at the Tates’ Bucharest estate and a male friend of the woman.

The Tates say the five conspired to falsely accuse them of human trafficking and rape, costing them their freedom and millions of dollars in income from their lucrative social media, podcasting and business ventures.

The lawsuit says the woman and her parents are residents of Palm Beach County, which is why it was filed there on Tuesday.

Romanian officials arrested the Tates in December and indicted them last month, saying the brothers forced seven victims into pornography and subjected them to physical violence. They remain under house arrest in Romania.

But lawyers Thomas Maniotis and Joseph D McBride in their lawsuit say the Tates are the victims of the Florida woman. They call her “a professional con artist” and say she pursued a sexual relationship with Tristan Tate in order to move to Romania, then tried to defraud the brothers.

When that failed, she conspired with the others to make false statements to Romanian and US embassy authorities that led to the arrests, the lawyers say.

“At no point did the Tate brothers engage in human trafficking,” the lawsuit says. The lawyers say the woman “is a serial liar, manipulator and schemer who exploits vulnerable, often wealthy men with good intentions for sexual, financial and emotional profit”.

The Associated Press is not naming the woman or her parents because she is the alleged victim of sexual assault. The other woman lives in the UK and the male friend in Virginia, US.

Romanian investigators said in their indictment that the Tates and two Romanian women formed a criminal group in 2021 “in order to commit the crime of human trafficking” in that country, the United States and Britain.

Andrew Tate was banned from TikTok, YouTube and Facebook for alleged hate speech and misogynistic comments, including that women should bear responsibility for being sexually assaulted. He has more than seven million followers on Twitter.

Several women in Britain also are pursuing civil claims against Andrew Tate, alleging they were victims of sexual violence.

In a recent interview with the BBC, Tate denied spreading a culture of misogyny and accusations that he manipulated women for financial gain.

The British-American brothers were jailed for three months before being released to house arrest in March pending trial. Prosecutors also confiscated the Tates’ assets, including 15 luxury cars, luxury watches and about three million dollars (£2.29 million) in cryptocurrency.

After listing several other men they claim the Florida woman has defrauded or exploited, the Tates’ lawyers say Tristan Tate met her through a dating app.

He invited her to a Miami business event the Tates’ company hosted in December 2021, and they had sex numerous times before Tristan Tate returned to Romania two weeks later, the lawsuit says.

It says the two kept in touch through texts, with the woman telling Tristan Tate she wanted to move to Romania and pursue internet modelling — a type of business the Tates have been involved with.

Tristan thought her modelling plans could work, but he tried to dissuade her, the lawsuit says. But in April 2022, “in the spirit of fun and adventure”, he paid for the woman’s flight to Romania.

The lawsuit says she stayed at the Tates’ estate for two days, where the pair again had sex. She then moved, as agreed, to another nearby home, but had access to the estate. They say she remained in the country only six days.

“She was not restrained in her movement, never confined, never controlled by any person nor was she threatened in any manner and always had free will,” the lawsuit says.

They say she soon conspired with another woman she met at the estate to defraud them of 200,000 dollars (£152,400) by falsely claiming they needed it for “something important”. When that failed, they say the Florida woman conspired with her male Virginia friend to contact the US embassy to falsely say she and the other woman were being trafficked.

That led Romanian officials to raid the home where she was staying, beginning the investigation into the Tates, the lawsuit says.
