Bhubaneswar, Nov. 11 -- A chilling revelation has emerged in the investigation of yesterday's Delhi explosion - a 'white-collar terror' module allegedly involving five doctors.

Security agencies have uncovered that the network, stretching from Kashmir to Faridabad, was formed by well-educated medical professionals who used their positions to avoid suspicion while planning the attack.

The key suspect, Dr. Umar Mohammad, a professor at Al-Falah Medical College in Faridabad and a native of Pulwama, is believed to have masterminded the operation. CCTV footage reportedly shows Umar driving the I-20 car used in the Delhi blast. His mutilated body was found at the site, and reports suggest he personally designed the attack blueprint.
