Looking for clues, investigators on Thursday examined the video cassette of a wedding ceremony that was taking place when a powerful bomb exploded in the Sankat Mochan temple.
Two PCOs in the city have also been identified from where the attackers had called up their operatives after the blasts, official sources said.
The investigators were scouring through the details of the telephone calls made to various places, including Nepal, Dhaka and Pakistan.
They have obtained details about the suspected terrorists from the owner of a shop which they had visited before the blasts at the temple and Cantonment Railway Station on Tuesday and left a cooker bomb, similar to the one used in triggering the explosions.
Based on the shopkeeper's version, they have prepared the sketch of the terrorists.
The video of the wedding ceremony was expected to throw light on the identity of the suspected attackers, who carried out the blast in the temple, they said.
Besides going through the video cassette, the investigators were also examining a magazine left by a saffron-clad man and a woman wearing a blue sari, near a shop in Godowlia market after planting live bombs near Dashaswamedh ghat.
The police also said that forensic tests have been conducted on the fingerprints of the duo obtained from the magazine.
