Police say those detained were behind a series of blasts in August in the western Indian city of Pune that wounded one person. Commissioner Kumar said a large amount of explosives were also seized during the arrests.
Indian Mujahideen is suspected in the 2010 bombing of a German bakery in Pune that killed 17 people and a 2008 blast in New Delhi that killed 30 people.
Last year, the U.S. State Department placed the group on its list of terrorist organizations. Indian Mujahideen has ties to Pakistan-based Lashkar-e-Taiba, which is responsible for the 2008 terrorist attacks on the India's financial hub, Mumbai, that killed 166 people. VoA.
