The special investigation team (SIT) probing the twin blasts at Kalamassery continued evidence collection along with the prime accused, Martin V.D., for the third day running on Friday.
He was taken to electrical shops at Palarivattom from where he had purchased the materials, which he allegedly used for making the improvised explosive devices (IEDs) for triggering the blasts.
The evidence collection lasted for around four hours. He was taken to three shops from where he purchased the remote control, LEDs, and battery. Besides, he was also taken to another shop from where he had purchased plastic bags. All shop owners reportedly recognised him.
