Dhaka: An inmate of a Hindu ashram was hacked to death in Bangladesh's Pabna town on Friday morning, police said. Nityaranjan Pandey, 60, a volunteer at a Hindu ashram, was murdered during his morning walk, a senior police officer said. His killing comes several days after a Christian grocer was killed in Natore and a Hindu priest in Jhenaidah, bdnews24.com reported. Pandey was working as a volunteer at the ashram for the past 40 years. The police said the assailants attacked him on neck and head from behind. The officer said: "We'll look into all possible aspects. We can't say right now if it was a militant attack." A number of murders carried out in similar fashion across the country in the past two years have sparked public outrage. The victims of these attacks include secular writers and bloggers, online activists, foreigners, members of various religious minorities and rights activists.
