Hope this answers your queston:
Most forced labour investigations have focused on the trafficking of women in to the sex trade in the UK. The Operation Netwing arrests in Bedfordshire are something different.
Fifteen of the men who were found living on the site were British citizens. The others mostly came from Poland, Latvia and Lithuania. In that context, the investigation is very unusual.
Women made up almost three quarters of the suspected victims - and half of all the cases related to allegations of sexual exploitation. The other half all related to forced labour - with more than 200 involving allegations of people being kept as domestic slaves. Some 50 people aged between 17 and 12 were found to have been abused in the sex trade. Two children under 10 were found to be working in forced labour.
Anti-Slavery International, a charity, says its best guess is that there are 5,000 people in some form of forced labour in the UK - but this figure is very tentative.
It says that in the two years until the end of March 2011, it received 1,481 reports of suspected trafficking. The top three nationalities of victims were Nigerian, Chinese and Vietnamese. British citizens were also in the top 10.
