Kathryn Taylor, from The Salvation Army’s modern slavery unit, said anyone identified as a potential victim from Thursday’s operation would be supported.
“It is vital that all victims of modern slavery are given the opportunity to reflect on their experience in a safe and supportive environment, and to gain access to the assistance they so desperately need and deserve,” she added.
“Once they have been identified as potential victims The Salvation Army works with survivors of this heinous crime as they begin the long journey to rebuild their lives and their trust in humanity.”
Support includes counselling, interpreters, legal and immigration advice, healthcare, financial assistance and safe accommodation to help people escape the “horrendous trade in human lives”.

A separate case over the alleged trafficking of Hungarian men into Britain is underway in London.
Laszlo Egeresi, 37, and Gabor Olah, 25, are accused of holding three of their fellow countrymen in debt bondage.
They allegedly forced them to survive on as little as £5 per week and pocketing the wages they earned doing low-paid work in kitchens and hotels, while using the men’s identifies to take out crippling payday loans they could not repay.
When the alleged victims tried to hold on to their pay or to escape, they were threatened with violence or physically assaulted until they returned to work, Kingston Crown Court heard on Thursday.
Egeresi denies four counts of arranging or facilitating travel of another with view to their exploitation between March 2015 and June 2017, while Olah denies two counts of the same charge.
