Newly released court documents in the U.S.-U.K. extradition case against Andrew Tate detail allegations that British authorities found extreme pornography involving animals and images and videos of minors on devices connected to him.

The filings are part of Britain's effort to extradite Tate and his brother, Tristan Tate, from the United States to face criminal charges in the United Kingdom. Andrew Tate faces additional allegations involving rape, assault, human trafficking, indecent images of children and extreme pornography. The Crown Prosecution Service has emphasized that the charges are allegations and do not constitute findings of guilt.

According to the extradition documents, investigators allegedly found images on a laptop attributed to Andrew Tate depicting sexual acts with live animals, specifically a horse and an eel. The documents describe the material as meeting Britain's definition of extreme pornography.

The filings also contain allegations involving a girl believed to have been 17 at the time. Prosecutors allege that a video showed Tate with the girl and another adult woman, and that messages indicated Tate was aware of her age. Authorities further allege that additional indecent images involving a child were found on devices associated with him.

British prosecutors say Tate faces 19 additional charges related to indecent images of children and extreme pornography, along with additional counts of rape, arranging or facilitating trafficking for sexual exploitation and assault occasioning actual bodily harm. The alleged offenses date from 2010 through 2017.

The allegations form part of a broader case in which British authorities accuse Andrew and Tristan Tate of using romantic relationships to recruit vulnerable women before coercing them into producing pornography. A Bedfordshire police detective alleged that the brothers used manipulation, threats and violence to maintain control over women who traveled to Romania to work in their webcam operation.

The Tate brothers were arrested in Miami in July after British authorities requested their extradition. They remain in U.S. custody while the extradition proceedings move forward, and a final hearing date has not yet been set.

Their attorney, Joseph McBride, has strongly rejected the allegations and criticized British authorities for withholding the identities of the accusers. He has argued that the allegations cannot be adequately challenged while key information remains redacted.

Both Andrew and Tristan Tate deny wrongdoing. The British Crown Prosecution Service has also stressed that its decision to prosecute is not a finding of guilt and that the defendants are entitled to a fair trial.
