UNODC's Toolkit to Combat Trafficking in Persons provides practical help to Governments, policy-makers, law enforcers, NGOs and others to enable them to tackle human trafficking more effectively. The Toolkit contains 123 tools and details a range of practices and methods currently in use throughout the world. These include checklists to help identify trafficking victims as well as guidance on interviewing victims and victim protection. Other tools help police to undertake cross-border investigations and advise government officials on how to ensure the safe repatriation of victims. These and many other current "best practices" are available for immediate use and adaptation worldwide.
