New Delhi: The National Investigation Agency (NIA) has made the eighth arrest in connection with last month's car blast near the Red Fort, officials said on Tuesday.

An NIA spokesperson said a team from Delhi has arrested key accused Dr Bilal Naseer Malla of Baramulla in Jammu and Kashmir. He was arrested from the national capital.

The NIA has found Bilal's involvement in the conspiracy behind the terrorist attack that killed 15 people and injured several others in the Red Fort area on November 10, a statement said.

"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," it added.

The NIA is continuing with its investigation into the conspiracy behind the deadly blast. The anti-terror agency is working closely with various central and state agencies to unravel all the threads of the conspiracy.

Meanwhile, a Delhi court on Tuesday extended the NIA custody of Amir Rashid Ali, an accused in the Red Fort blast case, for a further seven days. He was produced before Principal District and Sessions Judge Anju Bajaj Chandna on Tuesday.
