The Indian Mujahideen suffered a major blow a month back when its tallest leader, Yasin Bhatkal was arrested. Not only was Yasin arrested, but with him the agencies managed to take in Assadullah Akthar who too had become a major player in the outfit.
If the agencies are able to ascertain that it was the Indian Mujahideen that carried out the Patna blasts, then it would be interesting to see how the entire command structure of the outfit continues to work.
It would be safe to mention here that a majority of the brains behind this outfit are either in Pakistan and India. The think tanks are in Pakistan while the ground level operatives continue to hover around various states of India orchestrating horrific blasts.
