Delhi Police has recovered three 9mm cartridges from the site of the car explosion near the Red Fort that killed 13 people and injured several others on November 10, sources said. Two of the cartridges were live rounds while the third was an empty shell, officials said.
The discovery is raising questions among investigators because 9mm ammunition is generally used by security forces and police personnel. However, no weapon or pistol parts were found at the blast site. Police have already checked the ammunition issued to personnel deployed at the Red Fort that day. Officials said none of their rounds were missing, ruling out the possibility that the cartridges belonged to on-duty officers.
The blast, which shocked the capital, destroyed the car completely and caused widespread panic in the area. Authorities are continuing to examine the wreckage and document the aftermath of the high-intensity explosion. 
Meanwhile, police have also traced the movement of the Hyundai i20 car linked to the primary suspect, Dr. Umar Nabi, using 43 CCTV images obtained from across Delhi. The footage follows the car from a university campus in Faridabad to Old Delhi just hours before the explosion. Investigators stitched together the route using recordings from over 5,000 CCTV cameras across key checkpoints, highways, and districts in the Delhi-NCR region.
Dr. Umar Nabi was formally identified as the driver after DNA samples collected from the blast site were matched with those of his mother. The CCTV images provide a clearer timeline of his movements leading up to the attack.
