A former Pakistan Army Major, who has joined the ranks of Lashker-e-Taiba, LeT, is emerging as one of the masterminds of the Mumbai carnage and was in direct touch with arrested US terror suspect David Headley. The former armyman identified as Sajid Mir has turned out to be Headley's handler in Pakistan and was tasking the American to learn praying like Jews so that he could conduct a recce of Jewish Centre Nariman House in Mumbai and the premises of a newspaper in Denmark. Official sources said that Mir has been arrested in Pakistan but this could not be independently verified. The 48-year-old American-born Headley was arrested by the FBI sleuths at airport in Chicago in October this year for allegedly plotting to carryout terror strikes in India and Denmark. He told his investigators that he had learnt praying like Jews at the instance of Mir, who is now emerging as one of the mastermind of the terror strikes in Mumbai last November. Headley, according to the dossier of the FBI shared with Indian security agencies, said that he was conducting surveillance of the synagogue at the direction of Mir as he was under the wrong belief that the cartoonist of Denmark newspaper was Jewish. Statements of some of the witnesses who had either seen or accompanied Headley to Nariman House, also known as Chabbad House, have been recorded. <br/>
