Two men and a woman have been charged with human trafficking following raids at seven suspected brothels in Belfast.
The 21-year-old woman and the men, aged 33 and 46, are due to appear before Belfast Magistrates' Court tomorrow.
A 22-year-woman is also due before the court charged with controlling prostitution.
The raids, which were carried out on Friday, were part of the UK-wide operation.
Police said 12 women and three men who, they believe, were being forced to work as prostitutes, were rescued.
However, they would not say if any of them were rescued in Northern Ireland.
