(Indo-Asian News Service) Five Christian missionaries have been arrested in Orissa on a complaint by a group of Hindus that the former were inciting violence among tribes people, police said Sunday. The Mumbai-based Catholic missionary Karl Silva and his associates were arrested Friday and have been placed in judicial custody until Nov 4. Orissa has been a trouble spot for some time with Hindu organizations accusing missionaries working among tribes people of attempting to convert them to Christianity. Australian missionary Graham Staines working among leprosy patients and his two minor sons were burnt to death by a mob in 1999. Prime accused in the case Dara Singh has been sentenced to death.
