Police had to break into the flat in RAJUK Uttara Apartment Project, Sector-14, around 11:00am to recover the body of the retired professor of international relations of Jahangirnagar University.
He was alone in the flat as his wife and daughter were in the USA.
Professor Shafiq-ur-Rahman of JU confirmed the news to The Daily Star.
"I live in an apartment next to his. As the door was locked from the inside and there was no response after repeated knocks on the door, we called the police," he said.
