Andrew Tate and brother Tristan appear in a Romanian court over UK arrest warrant

Controversial influencer Andrew Tate and his brother Tristan have appeared in a Romanian court after the UK issued warrants for their arrest.

The internet personalities were detained by Romanian police on Monday night on arrest warrants over alleged sexual offences in Britain.

Bucharest's Court of Appeal postponed a decision on the warrant.

Andrew Tate, 37, and Tristan, 35, "categorically reject all charges", their representative said.

The men remain in custody.

Romanian Police said two arrest warrants were issued by British authorities for exploiting people in the UK.

A representative for the Tate brothers before the hearing described the arrest warrant as a "bewildering revival of decade-old accusations" leaving the brothers "dismayed and deeply troubled".

"They categorically reject all charges and express profound disappointment that such serious allegations are being resurrected without substantial new evidence," the statement said.

"They are fully committed to challenging these accusations with unwavering determination and resolve."

Their representatives claim the allegations cover 2012 to 2015.

Andrew, wearing a black hoodie, and Tristan arrived at court in handcuffs escorted by police.

They did not say anything to the gathered press, but as they were leaving court Andrew smiled when asked if he is ready to go back home.

Following the hearing, the brothers' lawyer Eugen Vidineac told reporters he knew little information regarding the warrant and did not know if new evidence was provided by the authorities.

In December, the Tate brothers, who are dual UK-US nationals, were ordered by a Romanian court not to leave Romania after the brothers made a request to visit their mother in hospital in the UK.

The brothers are being investigated by Romanian authorities over separate allegations of rape, human trafficking and forming a criminal gang - charges they deny.

They are accused of exploiting women via an adult content business, which prosecutors allege operated as a criminal group.

Two female Romanian associates were also named alongside the brothers in an indictment published in June, and seven alleged victims were identified.

Mr Tate has repeatedly claimed Romanian prosecutors have no evidence against him and there is a conspiracy to silence him.

He is a self-described misogynist and was previously banned from social media platforms for expressing misogynistic views.
