KUALA LUMPUR: Malaysia has detained a prominent Bangladesh activist, civil groups said Thursday, describing the government action as “harassment” against human rights defenders. Adilur Rahman Khan, secretary of the rights group Odhikar, was detained after arriving at Kuala Lumpur International Airport early Thursday, activists said. He was due to speak at a two-day conference organized by the Anti-Death Penalty Asia Network. Rights group Voice of the Malaysian People (Suaram) said Khan was being kept incommunicado at the airport’s immigration lock-up and appealed for his release. Immigration authorities could not be reached for comment. Malaysia often denies foreign pro-democracy activists entry into the country without giving explanation.
