Staff Reporter The investigators are grilling the four family members of slain Jama’atul Mujahideen Bangladesh (JMB) activist Mezba Uddin after picking up them from Comilla on Sunday to confirm the identity of their relative, said Commander Mufti Mahmud Khan, Director (Legal and Media Wing ) of the Rapid Action Battalion (RAB). Mezba’s brother identified one body that it was his brother, the RAB spokesman said. After primary interrogation, the elite force confirmed that Mezba became infamous militant in 2015, the elite force official said. He tried to influence his wife and mother to become militants, he said.

He also did not ascertain the whereabouts of the family members of Mezba. However, the investigators are still in dark about the identities of the two others, the said. On Friday, Mezba and two other operatives were killed during RAB raid in Nakhalpara, Tejgaon in Dhaka, they said. Mezbah’s fingerprints matched with the Election Commission database confirming his identity, said Lieutenant Colonel Emranul Hasan, Commanding Officer of RAB-3. Mezba, introducing himself as Jahid, rented a room of a flat on the fourth floor of six-storey “Rubby Villa” in Nakhalpara, he said. The elite force was also trying to identify the two other dead suspects, he added. Mezba had been missing for the last two months, and his father filed a general diary in this connection, said Nazrul Islam, Inspector (investigation) of Monohorganj Police Station. Mezba had been living in Dhaka for at least 10 years. He used to visit his family in every two or three months at Bhaduara village of Monohorganj upazila in the distrcit, he said.
