[JURIST] Bangladesh police on Tuesday arrested Fakhrul Islam Alamgir, the secretary general of the Bangladesh Nationalist Party (BNP) [party website], on counts of arson, bombings and vandalism. On Monday supporters of the BNP, the country’s main opposition party, led rallies [Reuters report] in Dhaka to mark the first anniversary of national polls, which the group has renamed “democracy killing day.” The rallies erupted in clashes between the ruling and opposition party activists, resulting in the deaths of four people.

The leader of the BNP and former prime minister, Khaleda Zia [Forbes profile; JURIST news archive], has remained confined to her office since Saturday as police and violent protesters swarm the outside. Meanwhile, Alamgir also remained inside the national press club, until he was arrested on his way to his car.
