Delhi Blast: Police Probe 3 Angles — What Did Dr. Umar Do Between 3:10 PM and 6:22 PM?

According to preliminary findings by the Delhi Police and forensic teams, ammonium nitrate, fuel, and a detonator were used in the blast. The Union Home Ministry has now handed over the investigation to the National Investigation Agency (NIA).

First Angle: Dr. Umar’s 3-Hour Mystery

Investigators are focusing on what Dr. Mo. Umar Nabi, the main suspect and a resident of Pulwama, was doing between 3:10 PM and 6:22 PM on the day of the explosion.

CCTV footage shows a white Hyundai i20 exiting the Red Fort Metro parking with a masked man inside, believed to be Dr. Umar.

Officials are trying to determine whether Umar met anyone, reconnoitered the area, or waited for peak-hour crowds before triggering the explosion. Reports suggest he remained seated inside the car for over two and a half hours without stepping out even once — raising questions about whether the blast was pre-planned or accidental.

Second Angle: The Faridabad Connection

The second angle revolves around Al-Falah University in Faridabad, where several doctors are under scrutiny. Police suspect a sleeper cell network linked to Umar, Dr. Muzammil, and Dr. Adil. Investigators are now mapping out all active and inactive members possibly connected to the cell.

Authorities are probing whether Umar personally carried out reconnaissance in Delhi or relied on others from this suspected network.

Third Angle: Unusual Nature of the Explosion

The third investigative line concerns the unusual nature of the blast. Unlike previous Delhi explosions, no nails, blades, or shrapnel were found at the site. Despite that, the damage was extensive — nearby vehicles were destroyed, yet no crater or major mark was left at the scene.

Experts are puzzled over how such massive destruction could occur from an explosion that left no visible trace on the ground.

NIA Takes Over the Case

Amid growing concern, the Ministry of Home Affairs transferred the case to the NIA. Earlier in the day, Home Minister Amit Shah chaired a high-level meeting with officials from the Intelligence Bureau (IB), NIA, and Jammu & Kashmir Police.

Meanwhile, Delhi Police conducted overnight search operations in Paharganj, Daryaganj, and nearby areas, checking hotel registers and tracking suspicious movements. Four people are currently under the police radar.

Security Tightened Around Red Fort

Following the blast, the Red Fort has been closed to tourists till November 13, while Gate No. 1 and Gate No. 4 of the Red Fort Metro Station remain shut as a precautionary measure.

Police confirmed that Dr. Umar blew himself up inside the car. His mother and two brothers have been detained in Pulwama for DNA testing. Another doctor from Pulwama, Dr. Sajjad, has also been taken into custody for questioning.

Route Map: From Faridabad to Delhi

Investigators have traced the 11-hour route of the i20 car, which started from Faridabad, Haryana, and ended near Delhi’s Sunehri Masjid, close to the Red Fort.

Authorities are now piecing together the timeline to understand Umar’s movements and motives, focusing on whether he acted alone or was part of a larger coordinated terror plan.
