Around 150 students, including activists of different student organisations, took part in the programme held at the base of Raju Memorial Sculpture.
Speakers at the programme demanded immediate arrest and punishment of those who attacked Imran in Jhenaidah and demanded the university authorities introduce an emergency helpline to ensure security of the students.
Addressing the human chain, former Ducsu member Tanbir Hasan Shaikat lamented attacks on DU students for protesting against injustice.
"Local ward member and his follower swooped on Duja general secretary when he protested against irregularities in distributing sacrificial meat for underprivileged families. The administration is yet to take steps although the incident has been reported in the media," he added.
Tarek Hasan Nirjhor, a student of mass communication and journalism, said the attack only highlighted the long-standing culture of impunity in the country.
Imran, a student of mass communication and journalism, and his younger brother came under attack allegedly by Abdul Aziz, a UP member of Ward No 2 at Banshbaria UP under Maheshpur upazila of Jhenaidah and his followers when they protested against the uneven distribution of sacrificial meat during the Eid-ul-Azha.
