Four people are to appear in court charged with offences linked to the suspected trafficking of Romanian women for the purposes of sexual exploitation.
Three men, aged 27, 31 and 52, and a 21-year-old woman, were arrested on Tuesday following searches in Omagh and Ballymena.
The four were charged on Wednesday with a number of offences including controlling prostitution for gain and using criminal property.
All are due to appear before Ballymena Magistrates’ Court on Thursday, and all charges will be reviewed by the Public Prosecution Service.
