A suspect in the Hyderabad blasts is understood to have revealed during the narco-analysis test that three foreign nationals involved in planning and executing the terror strikes were still in the city.
Syed Imran Khan, an executive in a private bank who underwent a narco test in Bangalore on Tuesday, however, denied having planted the bombs in the city, police sources said.
Khan, who is among the 15 persons against whom Andhra Pradesh police booked a criminal conspiracy case, also told the investigators that he had stored a consignment of 10 kg of RDX in his house before passing it on to other contacts in the city, the sources said.
Another suspect Kaleem alias Rafiq was on Wednesday subjected to a three-hour narco analysis test by the Forensic Science Laboratory in Bangalore during which he "made a lot revelations which cannot be disclosed at this point of time as it would hamper investigation into this grave issue which has national repercussions," Dr B M Mohan, director FSL, told PTI.
Imran and Rafiq were taken to Bangalore on Tuesday for narco tests. Both were arrested in connection with the May 18 blasts at Mecca Masjid and the smuggling of RDX from Bangladesh into the city in February 2007.
The police in Hyderabad believe that both the Mecca Masjid blasts and the August 25 twin blasts at Lumbini Park and Gokul Chat Bhandar were the handiwork of Bangladesh-based terrorist organisation Harkat-ul-Jihadi Islami.
The narco analysis tests are expected to help police in getting information about Bilal, believed to be the mastermind behind the blasts.
The Special Investigation Team of Andhra Pradesh, probing the Hyderabad blasts, will receive the report of the narco- analysis test conducted on two suspects in three or four days.
