Delhi Blast Case: Al Falah University Doctors Used Swiss App To Share Maps And Plans

Three doctors from Faridabad's Al Falah University are under investigation for their alleged involvement in the deadly car blast near Delhi's Red Fort that killed 13 people. According to investigators, the suspects used an encrypted Swiss messaging app, Threema, to share sensitive plans, maps, and instructions related to the attack.

The three accused - Dr. Umar Un Nabi, Dr. Muzammil Ganaie, and Dr. Shaheen Shahid - were reportedly in constant contact through Threema, a secure communication platform that does not require a phone number or email ID for registration. Police said the app was used for coordination, planning, and the exchange of operational details regarding the terror plot.

Officials believe that Umar, the man driving the red EcoSport car that exploded on Monday evening, played a central role in the conspiracy. The same car, now seized from Faridabad, is suspected to have been used to transport and store ammonium nitrate, which was used in the blast. Investigators described Umar as the most radicalised member of the group, acting as the link between all three doctors. He allegedly went underground, turning off his devices and cutting all digital communication after Muzammil and others were detained.

Authorities confirmed that the death toll rose to 13 on Thursday after another injured victim succumbed at LNJP Hospital. Several others continue to receive treatment.

Preliminary findings reveal that the group had conducted multiple reconnaissance missions across Delhi, identifying potential high-value targets for serial blasts. Officials said they were awaiting final orders from their handlers before the module was exposed.

According to investigators, the suspects may have created a private Threema server to maintain secrecy and avoid surveillance. This server was allegedly used to exchange maps, layouts, and coded messages related to the Delhi blast conspiracy. Sources added that "detailed planning, including location sharing and task allocation, took place through this private network."

Threema's encryption features reportedly made the investigation more challenging. The platform assigns each user a unique ID not linked to a SIM card or phone number and allows messages to be deleted from both ends without retaining metadata, making forensic tracing difficult.

Police suspect the accused used the app not only for encrypted chats but also for voice calls, file sharing, and design exchanges, ensuring that their communication remained untraceable. Agencies are now investigating whether the private server was hosted in India or abroad and whether other members of the module accessed it.

Early probes suggest that the suspects used Threema to transfer restricted materials and communicate in code. Officials also discovered that around 32 cars were being readied for potential blasts at key heritage sites and strategic installations across the capital. While one vehicle exploded near the Red Fort, three more have been recovered by police so far.

Authorities are continuing to track digital footprints, communication patterns, and the possible foreign links of the suspects as part of an extensive counter-terror operation.
