Stakeholders: Illegal working and modern slavery: Reporting a suspected case and further advice

How to report suspected cases

Any time you witness or have cause to suspect slavery or exploitation, you must make a referral directly to the FIS Illegal Working and Modern Slavery team in the first instance, giving as much information as possible, e.g. name/s, addresses, DOBs and NINOs (if you have them), details of the circumstances etc.

However if this comes to light as a result of a third party allegation of suspected slavery or exploitation then referral to RIS through the HumInt process is appropriate - see LPOG6900



If you need any advice or assistance in order to deal with an illegal working or modern slavery query, or if you receive a request for close working agreements, please contact the FIS Illegal Working and Modern Slavery Team
