New Delhi [India], November 18 (ANI): The National Capital's Patiala House Court on Tuesday received a bomb threat ahead of the production of the accused Jasir Bilal alias Danish by the National Investigation Agency (NIA) in the Red Fort bomb blast case before the Principal Sessions Judge.

The threat later turned out to be a hoax.

Soon after the threat, the Bomb disposal squad and dog squad team arrived at Patiala House Court. Rapid Action Force (RAF) was also deployed outside the Court.

Additionally, Security arrangements were increased following a bomb threat email received by the Patiala House Court.

On November 10, a blast near Delhi's Red Fort killed 15 people and injured many others. The prime accused, Dr Umar Un Nabi, a Kashmiri resident, was in the wheel carrying the explosive material.

In another significant breakthrough in the Delhi car bombing case, the National Investigation Agency (NIA) on Monday said it had arrested another key associate of the terrorist involved in the blast who had allegedly 'provided technical support for carrying out terror attacks by modifying drones and attempting to make rockets' ahead of the terror attack.

Jasir Bilal Wani alias Danish, also a Kashmiri resident, was arrested from Srinagar in Jammu and Kashmir by an NIA team that was in the Valley in the case.

In a statement, the NIA said its investigations have revealed that 'Jasir had allegedly provided technical support for carrying out terror attacks by modifying drones and attempting to make rockets ahead of the deadly car bomb blast which killed 15 persons and left over 30 persons injured.'

As per the NIA, Jasir, a resident of Qazigund in Anantnag district of Jammu and Kashmir, was an active co-conspirator behind the attack and had worked closely with the terrorist, Umar un Nabi, to plan the terror carnage that was executed them at around 7 pm on November 10 near the iconic Red Fort.

The NIA further said it continues to explore various angles to unravel the conspiracy behind the bombing.

Officials said several teams of the anti-terror agency are pursuing multiple leads and are conducting searches across states to identify every person involved in the terror attack.

This is the second consecutive arrest in the case as the agency on Sunday arrested the first Kashmiri resident, Amir Rashid Ali, who had conspired with the suicide bomber to carry out the terror attack. (ANI)
