A man named Md. Moktar Hossain, 40, who was arrested in connection with the murder of Jubo Dal leader Golam Kibria, has died while in the custody of the Detective Branch (DB) of Dhaka Metropolitan Police (DMP). Kibria, 47, the member secretary of Pallabi Thana Jubo Dal, was shot dead by masked assailants at a shop in Mirpur-12 on Monday evening. Following the murder, the case was transferred to the DB for further investigation. On Thursday, police arrested three suspects—Nazrul, Masum, and Zaman—from various locations in Shariatpur. They reportedly confessed to their involvement and claimed that the murder weapon was with Moktar. Acting on their information, DB officers detained Moktar from a garage in Pallabi around 6 p.m. the same day. According to reports, an angry crowd physically assaulted him during the arrest. The DMP confirmed Moktar’s death on Friday and announced the formation of a three-member committee to investigate the incident.
