Hyderabad: Investigators are believed to have obtained certain "clear clues" based on CCTV footage at the site of the twin blasts in Hyderabad and questioning of some jailed terror suspects here even as a letter purportedly written by Lashkar-e-Taiba (LeT) claimed responsibility.
Sources said that Prime Minister Manmohan Singh while being briefed by state DGP V Dinesh Reddy here about the progress in the investigations so far was told certain "clear clues" were obtained based on footage of the CCTV cameras at the scene and also questioning of some terror suspects lodged in jails here.
According to the sources, the video footage obtained from the site of blasts showed that three people were found moving suspiciously near bicycles strapped with explosives, just minutes before the explosions. Help of experts were being taken to enhance the footage for clarity.
"We are working in close coordination with the National Investigation Agency (NIA) and are hopeful of cracking the case soon," the DGP was said to have told the Prime Minister.
As multi-probe teams including from NIA analysed the footage and sought details of cycles bought locally, BJP's Andhra Pradesh unit president G Kishan Reddy said he received a threat letter purportedly written by Pakistan-based terror outfit LeT in which it claimed responsibility for the Dilsukhnagar bomb blast on Thursday night.
Police have questioned nearly 30 people in connection with the explosions but yet to make any arrest. 16 people were killed and over 100 injured when two bombs placed on bicycles went off within minutes of each other in which the handiwork of banned militant outfit Indian Mujahideen, which has links with LeT, is being increasingly suspected.
Reddy told reporters he received a letter by post yesterday written in Urdu and English languages.
However, he refused to give a copy of the letter saying he has handed it over to Abids police station. In the letter, the LeT purportedly stated that their next target is Begaumbazar, Reddy claimed. Begumbazar is another crowded wholesale market in the city.
When contacted, Abids police said "we have received a letter from Kishan Reddy today and it is being verified."

The Hyderabad police said Adam obtained his driving licence allegedly on fake residential address and they are verifying his antecedents.
