The body was hanging from the ceiling fan of a room in the flat of his sister Kohinur Nahar on Road No. 4 at Sector 4 on Friday morning, police said, citing the family.
He came to the flat to visit his sister five days ago, Uttara East Police Station OC Nur-e-Alam Siddiqui told bdnews24.com.

Sub-Inspector Abdur Rahim, who is investigating the death of Tanvir, said the members of Tanvir’s family had already brought the body down when he reached the house.
There were dark marks on the neck of Tanvir, he added.
