Indian police have arrested an alleged Kashmiri opeartive who they believe planned the Oct. 29 triple bombings in New Delhi, and are now hunting for seven others including the bombers, an official said Sunday. "We are happy to announce the working out of the recent blast cases (in New Delhi), "the city's police chief, K.K. Paul, told reporters. He said the breakthrough came with the arrest Thursday of Tariq Ahmad Dar, allegedly a key member of the Pakistan-based Lashkar-e-Tayyaba militant group, in Kashmir's city of Srinagar. Dar was brought to New Delhi on Friday for interrogation, and reportedly revealed a wealth of information about the plot, which police had initially blamed on Lashkar-e-Tayyaba. Lashkar is one of the most prominent of several Muslim militant groups fighting Indian security forces in Jammu-Kashmir, the only Muslim-majority state in predominantly Hindu India.
