The National Investigation Agency (NIA) has arrested Jasir Bilal Wani, also known as Danish, in connection with the Red Fort car bomb blast carried out by Dr Umar Nabi. Danish, from Qazigund in Anantnag district, was arrested from Srinagar. According to NIA sources, he gave technical support by modifying drones and even tried to build rockets. Investigators say he worked closely with Umar, who had allegedly planned for Danish to carry out a suicide (fidayeen) attack. The NIA is now probing deeper into the conspiracy, trying to uncover all the people involved in the attack. @@@
