Melksham: Human Trafficking Operation
Four Romanian men are being supported by police and partner agencies following a operation against Human Trafficking.
The joint operation saw officers from both agencies attend commercial premises in Melksham shortly after 9am.
The men, all aged between 25-45, were discovered to be working in exploited circumstances. All four men are now being looked after by the Salvation Army.
At this time no arrests have been made and enquiries are on-going.
Detective Sergeant Rob Findlay said: “These raids, further to others last week, again reinforce the reality that the net on human trafficking is indeed getting tighter.
“It also further emphasises our commitment as a force to fully investigate and robustly deal with this type of crime which sees people used as commodities.
“Operations like the one today simply aren’t possible without the information we get provided by our communities so I would always urge anyone with information on something they think is suspicious to report it, either to Wiltshire Police on 101 or direct to the our unit (Human Exploitation Team) on 01225 794630."
Alternatively people can contact Crimestoppers on 0800 555 111 where information can be left anonymously if they wish.
Major Anne Read, The Salvation Army's Anti-Trafficking Response Co-ordinator, said: "The Salvation Army is working with Wiltshire Police to rescue and support potential victims of trafficking. It is vital that victims of trafficking receive immediate access to specialised support. Our team has been working to assess the needs of the victims and ensure that they have access to accommodation and support at safe houses if needed.
"The Salvation Army operates a Government contract to provide vital help and support to adult victims of this pitiless exploitation which gives them the very best chance to try and recover through the comprehensive specialised services we can offer working with our partners.''
