DHAKA: Bangladesh police said on Friday a suspected Islamist extremist accused of carrying out a deadly attack on a prayer rally last month has been shot dead in a gunfight while in their custody. Shafiul Islam Don was being driven to a police station late Thursday when the Rapid Action Battalion (RAB) vehicle carrying him came under attack by suspected fellow extremists. The 22-year-old was killed in the gunfight that ensued, local RAB commander Shariful Islam told Agence France-Presse. “The attackers opened fire as they tried to snatch Don. We fired back in retaliation,” said Islam. “After a brief gunfight, they fled the scene. We found Don and another person’s body from the spot.” Police had arrested Don at the scene of last month’s attack at a prayer ceremony marking the end of Muslim holy month of Ramadan.
