In July 2024 Bangladesh was rocked by protests. They were sparked by anger at widespread corruption, and the reinstatement of a quota system that reserved 30% of civil service jobs for families of war veterans. An estimated 1400 people were killed in the protests which led to Bangladesh’s leader of 15 years, Sheikh Hasina, fleeing the country. After months of painstaking investigation, BBC Eye can now reveal how the police response to the protest unfolded and has verified a leaked audio recording in which Sheikh Hasina is heard authorising her security services to use lethal weapons against the protesters. We follow the story of one young man in particular, struggling to find justice for his 19-year-old brother who was among those killed.
