Juba Dal President Syed Moazzem Hossain Alal was released on bail from Dhaka Central Jail yesterday.
Leaders and activists of the youth wing of BNP received Alal with garlands after he came out of the prison around 11:45am. They chanted various slogans.
Earlier on October 2, the pro-opposition activists clashed with law enforcers in Naya Paltan and Kakrail areas and set fire to two vehicles when news spread that ruling party men foiled an opposition rally in Netrakona.
Police arrested Alal from near the party's central office on the following day in connection with the violence.
Later, a Dhaka court sent him on a two-day remand.
The law enforcers filed three cases against over 500 pro-opposition leaders and activists, including Alal, with Paltan and Ramna police stations in connection with the incident.
The Juba Dal president had recently secured bails from the High Court in the cases.
