Police filed a case against 2,000 people in Rangpur’s Gangachara upazila yesterday, after some 40 people were hurt in a clash between the law enforcers and BNP activists on Thursday.

Police say they have been able to identify an arsonist who set fire to police vehicle yesterday, during the clash with BNP activists at Nayapaltan.

Police yesterday charged truncheons and used water cannons on BNP men to foil their black flag programme in the capital's Nayapaltan.

Sporadic clashes take place across the country centring the special court verdict that sentenced BNP Chairperson Khaleda Zia to five years jail in the Zia Orphanage Trust graft case.

BNP’s sports affairs secretary Aminul Huq and 28 other activists of the party have been remanded in five lawsuits filed over last week’s clash with police in Dhaka.
