Meanwhile, it has come to light that Hyderabad city police commissioner Anurag Sharma had offered prayers at the famous Saibaba Temple in Dilshuknagar area, which is a few hundred yards away from the blast site, minutes before two blasts took place.
"The commissioner visited the temple at 6.30pm. As a security precaution, there were more police than usual," a police official said.
The first blast took place at 6.58pm on Thursday. Devotees throng the temple on Thursdays, which is considered special for Saibaba, to offer prayers making the area highly crowded.
The famous Saibaba temple at Dilsukhnagar witnessed a blast in 2002 in which two persons were killed and several others injured.Another senior official said two CCTV cameras installed on traffic posts at Dilsukhnagar bus stand.
However, it was found that one was not functioning. When asked about the possibility of capturing blast images by the camera, he said it may not be possible as they were focused towards traffic.
He, however, said they are in the process of going through the footage.
