Andrew Tate and his brother Tristan Tate were arrested Saturday in Miami by U.S. Marshals acting on a sealed warrant, hours after British prosecutors announced a major expansion of criminal charges against the social media influencers and formally requested their extradition to the United Kingdom.

The arrests took place outside the James L. Knight Center in downtown Miami, where Andrew Tate had been scheduled to appear at a bare-knuckle boxing event. Photos and video published by TMZ showed federal agents handcuffing the brothers. A Justice Department spokesperson confirmed that the arrests were made pursuant to extradition proceedings and in accordance with treaties and law enforcement agreements governing such transfers.

Bedfordshire Police in the UK said the brothers were taken into custody in connection with a long-running investigation into alleged sexual offenses dating back to 2012. The Crown Prosecution Service (CPS) announced it had approved a significant expansion of the case, bringing the total number of charges against the brothers to 59. Andrew Tate now faces 42 charges, while Tristan Tate faces 17. The new allegations include rape, arranging or facilitating trafficking for sexual exploitation, assault occasioning actual bodily harm, and offenses involving alleged indecent images of a child and extreme pornography. Tristan Tate also faces additional rape, sexual assault, and trafficking charges.

The CPS said the alleged crimes span from 2010 to 2017 and involve four additional alleged victims, bringing the total number of alleged victims in the UK case to seven. Malcolm McHaffie, head of the CPS Special Crime Division, stated,The CPS has requested the extradition of the Tates from the US. They have been arrested and await extradition proceedings to the UK.A law enforcement source told Fox News Digital that the charges stem from the United Kingdom and that the arrest warrant is expected to be unsealed to reveal the UK charges. The brothers are expected to make an initial appearance in the U.S. District Court for the Southern District of Florida early next week.

Assistant Chief Constable Karena Thomas of Bedfordshire Police said investigators had worked closely with prosecutors and international law enforcement agencies throughout the case.There is no place for male violence against women and girls, and we will continue to work tirelessly to support victims and investigate all reports made to us,Thomas said.

Andrew and Tristan Tate have denied wrongdoing. The brothers, who hold dual U.S. and British citizenship, rose to fame asmanosphereinfluencers, building millions of followers with content promoting hypermasculinity and male non-monogamy. They have denied criminal allegations filed against them in Romania and the United Kingdom. Neither the U.S. Marshals Service nor the Justice Department has publicly identified the basis for Saturday's sealed warrant. The brothers' attorney did not immediately respond to requests for comment.

The arrests mark a significant escalation in the legal troubles facing the Tate brothers, who have been under investigation in multiple countries. In Romania, they face separate charges of human trafficking, rape, and forming an organized crime group, which they have also denied. The UK extradition request adds a new layer of complexity to their legal situation, as they now face potential proceedings in both the United States and the United Kingdom.
