The National Investigation Agency on Thursday said it has arrested another man accused in the blast near Delhi’s Red Fort on November 10 that killed 13 persons.

The central agency identified the ninth person arrested in the case as Yasir Ahmad Dar, who is a resident of Jammu and Kashmir’s Shopian. He was arrested in Delhi.

Dar has been accused of being an “active participant in the conspiracy” behind the blast and taking an oath for “carrying out self-sacrificial operations”.

“Investigations by the anti-terror agency have further shown that Yasir was in close contact with the other accused persons in the case, including Umar Un Nabi,” stated the agency.

Nabi, a doctor, was believed to have been driving the car that exploded. Two days after the explosion, the Union government had described it as a “terrorist incident”.

The NIA further stated that earlier this month, it conducted searches at the premises of several persons it suspects were involved in the blast. The searches were conducted in Jammu and Kashmir, and several devices and “incriminating material” were seized, said the central agency.

On December 9, the agency arrested another person, Bilal Naseer Malla, from Jammu and Kashmir’s Baramulla, alleging that he harboured and provided logistical support to Nabi. He was also accused of destroying evidence related to the terror attack.

The central agency had on November 16 arrested an alleged aide to Nabi, who was identified as Amir Rashid Ali. The NIA alleged that the Hyundai i20 car used in the blast was registered in Ali’s name. This was the first arrest in the case.

A day later, the NIA arrested another alleged associate of the doctor, Jasir Bilal Wani alias Danish, from Srinagar. Wani is a resident of Qazigund in Jammu and Kashmir’s Anantnag.

On November 20, four more persons were arrested. They were identified as Muzammil Shakeel Ganai from Pulwama, Adeel Ahmed Rather from Anantnag, Mufti Irfan Ahmad Wagay from Shopian and Shaheen Saeed from Uttar Pradesh’s Lucknow.

Another man, identified as Soyab from Dhauj in Haryana’s Faridabad, was the seventh person arrested in the case on November 26. He was also accused of harbouring and providing logistical support to Nabi.

Hours before the blast, the police said that it had cracked an “inter-state and transnational terror module” in Faridabad and Uttar Pradesh’s Saharanpur.

The police said at the time that it had recovered 2,900 kg of improvised explosive device-making material in raids in several states.

The NIA has been conducting raids at locations in Jammu and Kashmir in the backdrop of the blast and the terror module case.
