The body of an 18-year-old polytechnic student was recovered from a residence in the Ambagan area of Moghbazar in the capital on Thursday.
The student was enrolled in the diploma engineering programme at Daffodil Polytechnic Institute (DPI).
The incident occurred at around 2:15pm on Thursday.
He was rescued in an unconscious state and taken to the emergency department of Dhaka Medical College Hospital (DMCH), where doctors declared him dead at around 2:45pm.
The student's sister, speaking at the hospital, said he had allegedly hanged himself using a waist belt tied to a ceiling fan in his room while other family members were unaware.
