LONDON (AP) — Influencer brothers Andrew and Tristan Tate were arrested Saturday in Miami after U.K. prosecutors said they brought further rape and sex trafficking charges against them.

Britain's Crown Prosecution Service said the new charges relate to four further victims and were brought after authorities received evidence from Bedfordshire Police in southeastern England. The charges include rape, assault, trafficking and offenses relating to "indecent images of a child and extreme pornography."

The charges announced Saturday, which bring the total number of alleged victims in the U.K. to seven, are the latest in a long-running international legal saga involving the brothers that has spanned the U.S., Britain and Romania. The brothers have denied wrongdoing.

An attorney for the brothers, Joseph McBride, blasted the latest charges as "filth and slander." In a phone interview Sunday, he said he was confident the extradition request would ultimately be denied.
