The Police Commissioner of Pune suggested that given the low intensity of the blast and extent of damage , the attacks were rather a mischief than a terrorist attack . However , given the sophisticated circuitry used in the devices , central agencies suspected the role of an terrorist organisation . It was also speculated that the bombings may have been carried out to avenge the murder of Indian Mujahideen commander Qateel Siddiqui or to avenge a central government recommendation that the ban on SIMI be extended for a few more years .

Few days ago , the Pune police had received a letter saying Qateel 's death would be avenged
