Former ambassador M. Maruf Zaman was reportedly abducted from the airport area on December 4, 2017, and held in a DGFI-run torture cell for 16 months. Zaman, known for criticizing Indian influence and the Hasina government, described harrowing conditions: loss of teeth from beatings, torn ligaments, untreated infections, and insect-infested cells. He endured extreme torture methods, including waterboarding, and witnessed fellow detainees disappearing. Guards occasionally hinted at secret executions.
