Banned in 2001 under POTA, SIMI’s strongest presence seems to be in Maharashtra, signalling a shift from homebase UP. The series of commuter blasts in Mumbai since last December shows the extent of its sway in the state. A network of its operatives, reportedly acting in tandem with the Lashkar-e-Toiba, was linked to the blasts on a Ghatkopar bus on December 2, 2002, and in a train at Mulund station in March that claimed 11 lives.
