Police have identified 11 additonal victims of a Melbourne immigration agent accused of drugging, raping and filming women across the state over seven years.

Frank Hu, 34, who ran a string of migration and travel agencies under the name Lakenest Group, allegedly lured many of his victims to his CBD office under the pretense of a job interview.

He was initially charged with 13 counts of rape relating to one victim.

Victoria Police and the Australian Border Force raid the offices of Frank Hu.

But court documents released to The Age on Friday show Mr Hu, also known as Xiadong Frank Hu, is now facing 235 separate charges relating to 12 different victims. The crimes are alleged to have occurred between 2013 and 2019.
