NEW DELHI: National Investigation Agency (NIA) on Tuesday arrested Dr Bilal Naseer Malla of Baramulla, Jammu and Kashmir, for allegedly destroying evidence linked to last month’s car blast near the Red Fort. His arrest in Delhi marks the eighth made in the case as investigators continue to widen their probe into the deadly attack.According to the NIA, Bilal also played a role in the larger conspiracy behind the November 10 explosion, which killed 15 people and injured several others in the busy Red Fort area. “As per NIA investigations, Bilal had knowingly harboured the deceased accused Umar Un Nabi by providing him logistical support. He is also accused of destruction of evidence related to the terrorist attack,” the agency said in a statement.The blast is being treated as a terrorist strike under the Unlawful Activities (Prevention) Act, with investigators linking it to a Jaish-e-Mohammed module involving radicalised young doctors and cross-border handlers. Several others connected to the accused have already been arrested, including a Faridabad resident who allegedly sheltered Umar Un Nabi shortly before the incident.The NIA said it is continuing to work closely with central and state agencies to trace every part of the conspiracy and identify all those involved in planning and executing the attack.
