New Delhi: The assailants who killed Bangladesh MP Anwarul Azim Anar in Kolkata were not paid the hefty sum they were promised by the person who hired them, Daily Star has reported.One Mohammad Aktaruzzaman, who lived in the Jhenaidah area from which Azim had been elected member of the Bangladesh parliament, had promised the killers close to Tk 5 crore. While Aktaruzzaman has fled to the US, where he has citizenship, investigators suspect that he is a member of the Purbo Banglar Communist Party (PBCP). Several reports have identified him as a friend of MP Azim’s and his associate in a gold-smuggling racket.Azim is a three-time MP of Bangladesh’s ruling Awami League party. Another report on Daily Star noted that the MP had made powerful enemies in his attempts to consolidate control over the illegal gold trade.The case is being investigated both by the Crime Investigation Department of Bengal and a team of the Dhaka Metropolitan police. Harun-or-Rashid, chief of the Bangladesh Detective Department arrived at the New Town Police station yesterday, ANI reported.Aktaruzzaman had rented a flat in Kolkata’s New Town suburbs and, according to Indian Express. He hired a woman, Silasti Rehman, a butcher – 24-year-old Jihad Hawladar, according to Daily Star – and two others to carry out the murder.Azim arrived at the flat on May 12 for medical treatment. He was killed on May 13. His body is learned to have been chopped into several pieces and disposed. Police are yet to find the parts.The killers only found Rs 4.30 lakh on Azim after they killed him, an investigating officer told Daily Star. All four accused are on judicial remand in Bengal. The Bengal CID is likely to seek Aktaruzzaman’s extradition from the US, even as Bangladesh home minister Asaduzzaman Khan has announced overt the weekend that his government is “working with India, Nepal, Interpol, and the US to bring Aktaruzzaman to Bangladesh.”
