This guideline is a revision of the publication released by IOM in 2005 titled "Guidelines for the investigation and prosecution of the crime of trafficking and protection of victims during law enforcement." The creation of this document has been beneficial for law enforcement officers in their effort to suppress trafficking in persons through law enforcement measures. The manual explains in practical terms the provisions of special legislation created to address the crime of trafficking in persons, and elaborates the underlying principles of case management and victim protection.More information about human trafficking on the website of IOM.
