Dhaka University Central Students' Union (Ducsu) Vice President (VP) Nurul Haque Nur says he was released from Dhaka Medical College and Hospital (DMCH) hastily so that police can apprehend him.
He made the allegation talking to journalists on the hospital premises on Tuesday morning.
Nur claimed DMCH authorities discharged him in a hurry so that police could arrest him in a case filed under the Digital Security Act.
However, DMCH Director General (DG) Brig Gen AKM Nasir Uddin told Dhaka Tribune: "We released Nur as per the recommendations of our 13-member medical board as his condition was sound enough to be discharged.
"He was released on Monday night and left the hospital on Tuesday morning. If he needs further treatment, our door is always open," he added.
After the discharge, Nur has been admitted to a private hospital in the capital.
Hasan Al Mamun, convener of Bangladesh General Students' Rights Protection Council (BGSRPC), confirmed the matter, saying Nur was shifted to a private hospital for better treatment.
He, however, refused to disclose the name of the hospital citing security reasons.
On December 22, Ducsu VP Nurul Haque Nur and 27 others were injured in an attack reportedly carried out by activists of Bangladesh Chhatra League and Muktijuddho Mancha, a platform of freedom fighter descendants, on the Dhaka University campus.
After the attack, Nur filed a complaint with Shahbagh police station for attempting to kill him, while three cases -- two with Shahbagh police station and another with Dhanmondi model police station -- were filed against him later on.
