Three 9 mm cartridges, two live and one empty, were discovered at the site of a recent car blast near Delhi's Red Fort, raising serious questions about their origin. The cartridges are of a type banned for civilian use, which adds complexity to the ongoing investigation. Despite this significant find, investigators reported that no firearms or weapon components were located at the scene, leaving them puzzled about the circumstances surrounding the explosion.

The Delhi Police Crime Branch has intensified its investigation, particularly focusing on Al Falah University. Two FIRs have been filed—one for cheating and another for forgery—based on evidence gathered so far. A team from the Crime Branch visited the university's Okhla office to request important documents related to individuals under scrutiny, as they explore potential misuse of academic or administrative channels leading up to the blast.

In a related development, investigators are looking into the activities of Dr. Umar Muhammad, who died in the explosion. Reports indicate that he had been seen moving around for hours before the incident. Dr. Umar had rented a room behind the Goyal Ultrasound Centre for ten days, with assistance from Shoeb, an electrician at Al Falah University. This room, which was found locked after the blast, has been raided by teams from the Delhi Police, NIA, and Haryana's CIA Nuh, as they believe it may hold vital clues.

CCTV footage from the nearby ultrasound centre is also under examination, showing the i20 car used by Dr. Umar, which could help reconstruct his movements prior to the explosion. Multiple teams from the NIA, Delhi Police, and Haryana Police are actively searching Nuh and surrounding areas to identify anyone who may have interacted with Dr. Umar or have information related to the explosive device. The recovery of the 9 mm cartridges, without any accompanying weapon, remains a perplexing aspect of this case as the investigation continues to unfold.
