The suspect is Md Nurul Chowdhury, 40, said Md Shafiqul Islam, additional commissioner of DB, at a press conference at the DMP Media Centre on Minto Road this afternoon. Acting on a tip-off, a team from the DB's Ramna Division arrested Nurul from a house in the Sunday-Society residential area in Uttara around 3:45am, said Shafiqul. Two walkie-talkies, two chargers, a fake passport, a fake ID card identifying him as an army major, and another fake ID card identifying him as a Rab deputy director with the rank of colonel were recovered from his possession, said Shafiqul, also the DB chief. DB officials also seized three mobile phones, 10 army uniforms, army medical books, various forms and pads, passport-size photographs of Nurul in army major and superintendent of police uniforms, fake army recruitment notices, and job application forms, he said. "Nurul used fake recruitment notices, application forms, ID cards, army uniforms, and photographs in uniforms of various forces to gain credibility through deception," the DB official said.
