Meanwhile, Home Secretary RK Singh says the Pune blasts appear to be a coordinated act. Two IEDs have not exploded. Maharashtra Home Minister R R Patil today said investigating agencies were probing all angles to determine whether any terror outfit was behind the low intensity serial bomb blasts that rocked Pune on Wednesday night. CCTV footage of the three blast sites are being explored, for which the ATS and NIA have been called in. 

"Whether it was a terrorist act or not will be determined only after proper investigations are carried out by Maharashtra ATS, city crime branch and central agencies," Patil told media persons after visiting the four blast sites on Jangli Maharaj Road in Pune.
