Mumbai, Jul 15: CCTV footages have been examined by Indian investigators looking for clues into the three blasts.
It is learnt that one of the footages have revealed ‘suspicious behavior’ of some people.
The blasts killed 18 people and injured many more.
Home Minister P Chidambaram has said the blasts could have been the work of a "small group" who had "worked in a very clandestine manner".
Suspicion among some officials and analysts has fallen on the Indian Mujahideen, a group which has claimed to have carried out similar attacks in the past.
Investigators who are going through the security camera footage and forensic evidence from the three sites are hoping to get a breakthrough.
