Led by Dr Kamal Hossain, the Oikya Front activists waiving black flags took out the procession from the National Press Club on Sunday afternoon.
When police stopped the activists after they marched about 100 metres, Jatiya Samajtantrik Dal-JSD chief ASM Abdur Rab and Nagorik Oikya Convener Mahmudur Rahman Manna protested.
The law enforcers later pushed them back into the Press Club.
Dr Kamal joined the procession in his car. Police arranged for its departure after stopping the march.
In a brief rally before the procession, the Oikya Front chief slammed the Sheikh Hasina administration for “not allowing the opposition to hold programmes”.
“These brave, honest boys of Bangladesh fought the Liberation War and waged the anti-autocratic movement. Now you are turning them into beasts, murderers,” he said.
Dr Kamal also demanded release of BNP chief Khaleda Zia from jail, claiming she is “seriously ill”.
Nagorik Oikya’s Manna announced a rally mourning Abrar in Dhaka on Oct 18. He said they would seek the official permission to use any venue.
