Question to the Home Office:

To ask the Secretary of State for the Home Department, how many victims of human trafficking had been previously identified as having been trafficked into the UK in each year since 2011.

The information requested is not held by the National Crime Agency (NCA) as it is not routinely recorded as part of the National Referral Mechanism process. However, the NCA's 'Strategic Assessment on the Nature and Scale of Human Trafficking in 2013,' which was based on additional information and intelligence, identified that there were three cases where a potential victim had experienced a secondary period of exploitation following recovery during the period 1 January
2013 to 31 December 2013. Similar intelligence assessments were produced in 2011 and 2012 which contained no data relating to the number of potential victims that may have been re-trafficked. Data for 2014 has not been published
yet.
