He was staying near Lalgola Madrasa in West Bengal’s Murshidabad district before the explosion.Earlier, the NIA arrested five persons including two women in connection with the blast. The NIA had made its fifth arrest on Friday when they apprehended Zia-ul-Haque, a close associate of Rezaul Karim, another suspect in the blast, from Malda district. Two persons died in the accidental blast inside a house at Khagragarh in Burdwan town on October 2. The NIA handed over the probe report a week later.Meanwhile, Zia-ul-Haque, who was arrested on Friday in connection with the Burdwan blast, was sent to seven-day NIA custody by a Sessions Court in Kolkata.Producing the accused to the court of Mumtaj Khan, NIA counsel Shyamal Ghosh prayed for 14 days’ remand but the court granted seven days only.The NIA counsel pleaded that since the probe was in an early stage, a longer custody would enable the investigating agency to gather more information from the accused.The agency said that Haque was a member of the JMB and was also in contact with absconding Yusuf Sheikh alias Moulana Yusuf.The NIA on Friday arrested Haque for allegedly indoctrinating youth for training by showing ‘Jihadi’ videos related to Gujarat and Assam violence.
