New details have emerged in the Delhi blast case. The terrorists involved in the 10/11 Delhi blasts reportedly used a specific method to communicate among themselves, called a “dead drop.” Communications were taking place amongst them through emails, but not directly. A person would draft an email and then save it as a draft; others would log onto the very same account and read it and follow the plan.

A powerful explosion shook the Lal Quila area of Delhi in the evening on November 10. The incident was described by the central government as an act of terrorism. Three doctors, namely Muzammil Shaikh, Umar Nabi, and Shaheen Saeed, have come under the scanner of investigators. It has also become clear that the trio had links with the terror module of Pakistan-based Jaish-e-Mohammed.

Investigators now have new information that these doctors used email accounts to exchange information. They wrote their plans in the draft folder, which the others would then log in and read. None of the emails were ever sent, for they wanted to avoid leaving any digital footprint.
