The BNP will stage demonstrations in all cities and district towns on Thursday to protest "barbaric" police action and mass arrests of the party's leaders and activists in front of its Nayapaltan central office on Wednesday.
Party standing committee took the decision at an emergency meeting at night, said a press release.
Following the police action at Nayapaltan, the BNP standing committee, the highest policy-making body of the party, sat in the meeting to work out its next course of action.
The BNP policymakers strongly condemned and protested the "unnecessary, unwarranted and cowardly" police attack and firing that left a Swechchasebak Dal leader dead and injured many others centring the party's December 10 rally.
They also protested the arrest of a good number of party leaders and activists.
The meeting demanded the unconditional release of the attested party leaders and activists and called upon the police administration to stop such attacks, arrests, harassment and repressive and suppressive acts.
Meanwhile, the BNP postponed the special press conference that was scheduled to be held at a city hotel on Thursday at 3:30pm.
BNP medical cell member Sayrul Kabir Khan said the fresh date and time of the press conference will be announced later.
