NEW DELHI: Though the Special Cell has been working round-the-clock on the twin blasts that took place at the Jama Masjid in the Walled City area on Friday, it has not achieved any major breakthrough.

It is learnt that apart from the involvement of an extremist group, the angle of mischief by some local criminal elements is also being probed by the Special Cell. The use of a crude bomb, apparently assembled using materials easily available, indicates that someone who had no access to lethal explosives was behind the low-intensity blasts.

Also, the culprits knew the bombs placed near the tank at the centre of the mosque would not cause much damage as it was an open area. "In many such cases, it has been found that the motive is to create communal disturbance. As was seen in the recent blasts in Varanasi," said a senior police officer.

Probe continues

The police are also trying to find out if someone trained by Pakistan-based Lashkar-e-Taiba militant Abdul Karim Tunda was involved in manufacturing the improvised explosive devices. "As we are probing all possible angles, the role of Tunda's men, some of who are still at large, cannot be ruled out," said the police officer.

Experts are trying to find out the unique features of the bombs used. "In several cases, the type of bomb used provides valuable clues regarding the outfit behind the incident. Cadre-based organisations carry out all their attacks in a similar fashion," he added.

On Saturday, the Special Cell interrogated about 15 people. Though a majority of them have been let off, some are still being grilled. Two of the 14 injured are still in hospital.
