Interns at Dhaka Medical College Hospital (DMCH) formed a human chain in front of the central Shahid Minar on Wednesday morning protesting the attack on their fellow Dr Sazzad Hossain.
Condemning the attack they demanded immediate arrest and punishment of the attackers around 11am.
"We also demanded the concerned to identify the attackers within tomorrow (Thursday). Otherwise, we will go on strike," he added.
On Monday night, some students of Dhaka University beat Dr Sazzad Hossen up at Central Shahid Minar premises without any valid reason, said the victim.
"Around 9pm of August 8, I sat on the premises of central Shahid Minar. Suddenly, some students of the University of Dhaka (wearing T-shirts with the logo of Dhaka University) appeared and started asking me about my identity and institution," Dr Sazzad wrote on his Facebook timeline.
He added, "When I told them that I am a student of Dhaka Medical College, they wanted to check my ID card. As I failed to show my ID card at that moment, they started beating me and hurled abusive words at me.”
Shahbagh Police Station Officer-in-Charge Moudut Halder said a case was filed in this connection against some unidentified people.
