Wasim Akram Malik, arrested for his alleged role in the September 7 Delhi High Court blast, was on Friday remanded by a city court to NIA custody for three more days.

NIA pleaded that he needs to be further interrogated for nabbing a few more of his accomplices.

Special NIA Judge H S Sharma allowed the National Investigating Agency to quizz Malik, a Jammu and Kashmir native studying Unani medicine in Bangladesh, for three more days after the agency said they have to arrest some more persons linked to the case.

Malik was produced before the court after the expiry of his 14-days' NIA custody. The investigators had termed Malik as a 'key link' in the conspiracy behind the blast outside Gate 5 of the high court on September 7, leaving 15 people dead and over 70 injured.
