Andrew Tate and his brother Tristan have been detained in Romania after European arrest warrants were issued by the UK, his representative has said.
The allegations, including sexual aggression, cover 2012 to 2015, his team said.
The Tate brothers “categorically reject all charges”, the statement said.
Romanian police said European arrest warrants for two men were issued by UK authorities for sexual offences on Monday.
The alleged offences also included exploiting people in Great Britain, the Romanian police statement said.
The two men were presented to the prosecutor attached to the Bucharest Court of Appeal, who ordered their detention for 24 hours, police said.
A representative for social media influencer said the court will make a decision on Tuesday as to whether to “execute the mandate”.
They 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.”
