MIAMI — Andrew Tate kept “extreme” bestiality porn, including images that showed a person having sex with a horse and a eel, according to documents released by prosecutors in the UK.

British authorities made the revolting claims as part of their request for the US to extradite controversial “manosphere” influencers Tate, 39, and his brother Tristan, 38, to the UK to face rape and sex trafficking charges there.

The image was in Andrew Tate’s possession on or before July 18, 2015, and “portrayed, in an explicit and realistic way, a person performing an act of intercourse with a live animal, namely an eel,” docs filed in federal court in Miami on Monday and obtained by The Post claimed.

It was “grossly offensive, disgusting or otherwise of an obscene character and a reasonable person looking at the image would think that any such person or animal was real,” the docs added.

Another image allegedly found on or before July 18, 2015, showed someone “performing an act of intercourse” with a horse, they claimed.

Dual US/UK citizens Andrew and Tristan are currently locked up in federal detention in Miami while they fight extradition to the UK.

US Magistrate Lauren Louis ruled last month that the brothers should remain behind bars during what could be a months-long court battle.

The Tate brothers deny all claims.
