A Chattogram court on Tuesday sentenced a former commander of banned militant outfit Jamaat-ul-Mujahideen Bangladesh (JMB) to 20 years imprisonment in two cases filed over the Explosives Substances Act and the Anti-Terrorism Act. The convict was Ershad Hossain alias Mamun, son of Riazul Islam of Dinajpur district. Judge of the Chattogram Additional Session Judge Court-4, Shariful Alam Bhuiya announced the verdict. The court also fined him Tk 20,000 and if he failed to pay the money he will be jailed for one year more. According to the prosecution, police arrested Ershad from a house in Akbar Shah area and seized some explosives, bomb making materials and some books from his possession on March 23, 2015.
