The Delhi police has been insisting that the explosion was not aimed at causing any major damage but to create a scare. Sources said the blast had the typical signatures of terror outfit Indian Mujahideen.
A team of Delhi police's special cell investigating the case conducted raids in Pilkhuwa in Uttar Pradesh on Thursday night and picked up one youngster. The youngster was picked up for his links with a terrorist, who used to live in his village two decades ago.
In Lucknow, Special DG (Law and Order) Brijlal said a person, Gulfam, was picked up from Pabla village in Pilkhua. He, however, refused to confirm whether the Delhi police detained the youth. "We have no official confirmation on this from the Delhi police," he said.
Locals, however, claimed that police picked up at least six to seven youngsters from the locality for questioning.
The police had recovered some shrapnel, a battery-like object and ammonium nitrate from the spot of the blast. Nails and bolts were packed and a detonator was attached to the timer.
Sources said this pointed to the possible involvement of the Indian Mujahideen, as the crude bomb had signatures of the terror outfit's methods. However, senior police officials refused to confirm the involvement of the Indian Mujahideen.
Delhi Police Commissioner B K Gupta on Thursday said that it was too early to say anything about the motive of planting the bomb, as it did not have the potential to cause any fatality or major damage.
Gupta visited the Delhi high court to attend a meeting chaired by Chief Justice Deepak Misra to review the security of the complex in the wake of the incident.
