A little over 36 hours after the twin blasts in Hyderabad here are the key developments in the investigations in the case:
CCTV footage has been used to zero in on suspects
One suspect has also already been identified on the basis of the CCTV footage, reported the Hindu.
Unnamed sources were quoted as saying that the suspect, in his early thirties, is seen riding a bicycle and heading towards one of the blast sites about 15 minutes before the blast and was seen leaving on foot.
“The bicycle was the one typically used by labourers. The bag could have contained the IED,” a police officer is quoted as saying, adding that the face isn't clearly visible.
CNN-IBN reported that five persons have been spotted in the footage on cycles and the police are attempting to track them down and verify their identities.
The Times of India reported that there were two CCTV cameras near the blast site and are being examined by local police. However, how useful the footage will be only time will tell with police officials saying that the footage may be a little too grainy for them to pinpoint persons who have been involved in carrying out the blasts.
The police has also denied that the cameras were not working and said that one of the cameras may have been knocked out after the blast but definitely was functioning at the time of the blast.
"The video footage is being analysed by our team, but so far no useful evidence has been found, " Hyderabad commissioner Anurag Sharma was quoted as saying by the Times of India.
Blast signature different from those used in Pune blasts
Investigators have found that there were similarities between the serial blasts carried out in Pune last year on Jangli Maharaj road, reported The Indian Express.
"The National Security Guard has reported the finding of a quartz timer or an electronic clock of some sort. This is a bit like the Pune blast timers. But we are only saying at this stage that a timer device was used," an unnamed senior police official was quoted as saying.
The bombs were reportedly kept elevated in order to target the nearby eateries and could have set off LPG cylinders that were in them, said investigators, with some suggesting that the improvised explosive devices were kept elevated to maximise the amount of damage that could be caused.
The amount of shrapnel used in the blast was also much lower than the Pune blast but investigators aren't sure if it was swept away by people when they attempted to rescue victims.
The fact that bombs were intended to explode with maximum impact in a particular direction is a sign of the involvement of terror group Indian Mujahideen, the Times of India reported.
The report quoted unnamed sources saying that the terrorists used over one kg of ammonium nitrate, 400gm in one bomb and 700gm in the other and packed them in aluminum containers with shrapnel.
