Mumbai: Investigators scouring security camera videos may have spotted possible suspects of Wednesday's triple explosions in three to four suspicious people near the Opera House blast site, sources within intelligence agencies said.
At least 17 people were killed, and later a severed head was found on one of the blast sites taking the toll to 18, apart from over 130 injured in coordinated explosions that tore through busy hubs in Mumbai's rush hour on Wednesday evening.
Sifting through Close Circuit Television (CCTV) tapes of cameras around the Opera House site, which saw the maximum casualties at 11, investigators have reportedly spotted three to four people talking on cellphones standing in the same spot for over 90 minutes.
They have also learnt more about the bombs. Described as improvised explosive devices (IEDs), the bombs were made from a mixture of ammonium nitrate, Tri-Nitro Toluene (TNT) and fuel oil, which were set off by cellphones alarms. Ball bearings were used as shrapnel.
