Eight men have been arrested in connection with human trafficking and sexual exploitation, police said.
An investigation was launched last month in Bristol after two women, aged 18 and 21, reported incidents of sexual exploitation committed against them at a property in the Eastville area of the city.
The women also gave details surrounding the arrangement of forced marriages, Avon and Somerset Police said.
As a result of police inquiries, six warrants were carried out at four addresses in Bristol and two in the Hockley area of Birmingham.
A 42-year-old man from Birmingham was arrested on suspicion of trafficking, rape and assault. He has been bailed for these offences but has been remanded in custody in relation to an outstanding warrant.
All the other men arrested were from Bristol.
Two men, aged 38 and 36, who were arrested on suspicion of trafficking have been released on bail.
A 24-year-old man was arrested on suspicion of money laundering and was also bailed.
