Nicolae Ionita, aged 24, met the victim in Romania and travelled to the UK with herÂ in September last year.
The victim made plans for the pair to seek employment in Milton Keynes but after two days,Â Ionita convinced his victimÂ to move to Middlesbrough, where his sister Claudia Ionita, 30, lived.
CRIME: Five men hunted over stabbing in Sheffield street Over the next month, the brother andÂ sister, both of no fixed abode,Â pressurised their victim into working as a prostitute in the town, before the three of them moved to Sheffield in October.
For a month, the victim, who cannot be named for legal reasons, was forced to work as a prostitute in SheffieldÂ while living in the Hillsborough area.
Detective Constable Gareth Bryant said: 'The pair forced the young girl, who was expecting a job, money and a nice place to live, to work as a prostitute in both Middlesbrough and Sheffield, telling her that it was her only option.
'Together, and especially Nicolae Ionita, they used the victim's dependency on them as a means of exploiting her. 'They controlled where she stayed and who she spoke to, monitoring her phone-calls with friends and family and telling her what to say and as such, was never able to tell anyone what was actually happening to her.Â 'However in November 2017, she found the confidence to phone home and tell them what was happening. They encouraged her to tell someone and one day she left the house where she was living and ran toward two members of the public. 'They described the woman as scared and appearing dishevelled, as she tried to ask them for help. As she spoke little English, they helped her to flag down a police car.'
In June, both Nicolae and Claudia IonitaÂ were due to go on trial for two counts each of causing or inciting prostitution for gain.
The siblings entered guilty pleas at the start of the trial and were bailed until yesterday, where they were each jailed for 21 months.
DC Bryant said: 'The woman has been so incredibly brave throughout this entire process, from coming forward to report what happened and working with the investigative team to provide statements and evidence.Â 'She even said she would travel back from Romania, where she returned home to be with her family, if she needed to testify against the pair.Â 'Her courage is a testament to getting the Ionitas to court and now behind bars. This was a complex investigation which saw two people exploit a vulnerable young woman.Â 'Protecting vulnerable people is an absolute priority for us and we will always do what we can to identify those who exploit people for their own selfish gain or gratification.'Â Detective Inspector Claire Mayfield, added: 'This has been a protracted investigation that has seen the courage of the victim tested over this time.Â Â 'She has demonstrated great courage in not only disclosing the abuse but then supporting a criminal investigation from her home in the European Union. Â 'The team have worked together with the assistance of the Romanian Authorities to bring this to a successful conclusion, sending the message that the exploitation of vulnerable individuals will not be tolerated.'
