New Delhi: In the ongoing investigation into the vehicle attack near Red Fort, the fourth car, a Maruti Suzuki Brezza, has been located, according to media reports. The vehicle was found parked on the campus of Al Falah University in Faridabad, Haryana, which is emerging as a key hub linked to the suspects’ activities.

The investigation began after a white Hyundai i20 exploded close to Red Fort on Monday evening, killing 13 people and injuring around 30. Authorities subsequently traced a second vehicle, a red Ford EcoSport, to Faridabad.

Earlier, a Maruti Suzuki Dzire was reportedly seized on Monday, with authorities recovering an assault rifle and ammunition from inside the car.

The EcoSport, bearing registration DL10 CK 0458, was recovered late Wednesday, abandoned in the city. Sources said the Ford EcoSport is registered in the name of Dr Umar Nabi, who was allegedly driving the exploded Hyundai i20.

They said Umar used the EcoSport for reconnaissance activities.

On Monday, authorities busted a "white collar terror module" with links to terrorist outfits Jaish-e-Mohammed and Ansar Ghazwat-ul-Hind and spanned across Jammu and Kashmir, Haryana and Uttar Pradesh. They seized 2,900 kilograms of explosive substances and arrested eight people, including three doctors linked to Al Falah University in Faridabad.

Hours later, a high-intensity blast ripped through a slow-moving car in the heavily crowded Red Ford metro station area, killing 13 people and injuring several others. A DNA test on Thursday confirmed that Dr Umar was behind the wheels of the exploded car.

Police teams on Wednesday visited the Al-Falah University and the residence of Dr Muzammil Ganaie, one of the prime suspects arrested in the case. They questioned several doctors and students in the university.
