Police have laid fresh charges against a man accused of operating a sexual slavery ring in Brisbane.
Matthew James Markcrow, 35, was remanded in custody earlier this month after police raided two properties in South Brisbane and Mount Gravatt East.
Detectives allege he drugged and held women as young as 17 for prostitution, in what police described as "horrendous" example of modern-day slavery.
He is also accused of tattooing the women as his property and controlling their living, financial and work conditions.
Nine alleged victims have now come forward to police after a public appeal.
Mr Markcrow has been charged with 13 new offences, including six counts of conducting business involving servitude, four counts of supplying dangerous drugs, and one count of grievous bodily harm.
He is due to reappear in the Brisbane Magistrates Court on Wednesday on a total of 23 charges.
Crystal Sawyer and Hannah Stead, both aged 23, were also charged earlier this month as part of the investigation.
Detectives are urging anyone else with information to come forward.
