History
The Police Bureau of Investigation was formed on 18 September 2012 to investigate "sensational" and difficult cases. In November 2016 Bangladesh Police burned down shanties of Santals in Gaibandha and the PBI was tasked to identify the responsible police officers. They were charged with the investigation of the 2017 South Surma Upazila bombings. PBI has been tasked to collect evidence from terrorist attacks such as the 2017 RAB base suicide attack and the raid on the militant base in Sitkundia. The agency is responsible for the investigation of human trafficking.
