North South University (NSU) teacher Mubashar Hasan has said that he had been kept in a dark room for around one and a half month.
"There was small room, which was always kept shut," Mubashar said.
He broke down in tears while talking to reporters in front of his Banasree residence.
Mubashar said, “The captors used to argue among themslves whether they would kill me or not."
Mubashar, assistant professor of Political Science department at the NSU, returned home early hours of Friday.
He was provided with a torn and shabby bed where he used to sleep, the teacher said that leftover food was given him by his captors.
"I heard the voice of some men who talked about money," he went on saying, “They took Tk 27,000 which I had with me”.
“I was blindfolded when they left me somewhere on the Airport Road.”
Before releasing Mubashar from the car, they said, “If you look back, we will kill you".
Replying to a query, he said, he was going to his residence by a Uber taxi while some men intercepted the car he was riding.
They forced him out from the taxi and pushed him into a microbus on November 7.
