Supplementary chargesheet names three Jammu and Kashmir men, taking the total accused to 13, and alleges one was involved in manufacturing and storing IEDs for the terror module.
The ED said the attack was carried out by Jamesha Mubeen (suicide bomber) and others as an ISIS-inspired terrorist attack using a modified car loaded with explosives.
The probe into the Delhi blast has revealed that terror groups like Jaish-e-Mohammed are increasingly recruiting highly educated professionals, including doctors.
Using the pooled money, the group had allegedly purchased around 26 quintals of NPK fertiliser approximately worth Rs 3 lakh from suppliers in Gurugram, Nuh and nearby towns.
