Kochi (Kerala): The investigation reveals that Improvised Explosive Device( IED) kept in a tiffin box was used to trigger the multiple blasts at Kalamassery Convention Centre on Sunday, sources said.
One person was killed and 40 were injured in the blasts. Among the injured, the condition of seven persons was critical.
Kerala DGP Sheik Darvesh Saheb ruled out the initial reports of the explosion taking place due to an electric short circuit and confirmed that the explosion was a bomb blast.
Sources have also confirmed that it was an act intended to create terror. About 2,000 people gathered for prayers at the convention centre at the time of the blast.
A four-member team from the National Intelligence Agency (NIA) from Kochi was at the spot. Sources confirmed that the NIA team from New Delhi had left for Kerala to take over the investigation.
