A mysterious blast took place outside one of the gates of the Delhi high court, just a stone's throw from India Gate on Wednesday afternoon.
An obscure organisation going by the name of Lashkar-e-Tohfa had warned in a letter to the stationmaster of New Delhi railway station on May 14 that bomb blasts would take place at many places in Delhi on May 25. But the Delhi Police didn't take the threat seriously.
"It seemed like a hoax, so no high alert was declared," said a senior police officer.
But a blast did take place, even though it was a low-intensity explosion that hurt no one.
A crude device was planted near the front wheels of a lawyer's car. The nature of the explosives is yet to be ascertained but the police have recovered iron shrapnel from the spot.
"The blast took place in the service lane, which is not a controlled area. It was a minor explosion in a plastic bag and no other vehicle was damaged," said Dharmendra Kumar, special commissioner of police (law and order).
Delhi Police commissioner BK Gupta and senior officers of the crime branch and special cell inspected the spot.
A bomb squad of the National Security Guard was also pressed into service to collect evidence soon after the blast.
"A powder and the remains of the plastic bag have been sent for forensic examination," Kumar said.
The nature of the explosives is yet to be ascertained but the police have recovered iron shrapnel from the spot.
The investigators have ruled out the involvement of the lawyer in front of whose car the blast took place on Wednesday.
