Mohsin Chaudhary, the man who reportedly planned the Pune blast, is probably in Karachi, say sources in the Anti-Terror Squad, which is investigating the blast.
Sources say 35-year-old Chaudhary, who is the head of Pune branch of the Indian Mujahideen, escaped to Pakistan three days after the terror attack in the city.
Last month, a bomb exploded at Pune's German Bakery on a Saturday evening. Seventeen people were killed, most of them young students and professionals.
