Guwahati (Assam) [India], November 13 (ANI): Assam Chief Minister Himanta Biswa Sarma on Thursday morning said that 15 people have been arrested across the state for 'offensive' posts on social media following the blast near Delhi's Red Fort that claimed at least 12 lives and left several injured.

'In connection with the offensive social-media posts following the Delhi blasts, 15 persons have been arrested across Assam so far.

In addition to the 6 arrests made yesterday, overnight we have arrested the following persons also: Rafijul Ali (Bongaigaon), Forid Uddin Laskar (Hailakandi), Inamul Islam (Lakhimpur), Firuj Ahmed @ Papon (Lakhimpur), Shahil Shoman Sikdar @ Shahidul Islam (Barpeta), Rakibul Sultan (Barpeta), Nasim Akram (Hojai), Taslim Ahmed (Kamrup), Abdur Rohim Mollah @ Bappy Hussain (South Salmara).' Sarma posted on X.

'Assam Police remains uncompromising against those who glorify violence,' he added.

This comes after Sarma, on Wednesday, said that the administration aims to catch those supporting terrorism.

'We will catch those who support terrorists and will take action against them. These people are trying to deteriorate the situation in Assam,' he told reporters.

Intelligence agencies on Thursday revealed a larger terror conspiracy linked to the deadly car blast near Delhi's Red Fort that claimed 12 lives, with sources saying that the suspects had allegedly planned to prepare around two old vehicles with explosives to carry out coordinated attacks across multiple locations.

According to intelligence agency sources, the ongoing investigation has expanded after it was discovered that the accused had already begun modifying an i20 and an EcoSport vehicle for potential use in the attacks. Investigators are now examining whether other similar vehicles were being readied as part of a broader plan to execute serial blasts.

'After the i20 and EcoSport, it came to light that preparations were underway to ready two more old vehicles which could be fitted with explosives,' an intelligence source told ANI.

Further, investigation agencies informed that around eight suspects were allegedly preparing to execute coordinated explosions at four locations, with each pair assigned to a specific target city.

Preliminary investigation indicates that the accused groups had intended to move in pairs, each carrying multiple improvised explosive devices (IEDs) for simultaneous attacks. Among those under scrutiny are individuals linked to past terror cases, including Red Fort blast accused Dr Muzammil, Dr Adeel, Dr Umar, and Shaheen.

According to sources, the police were able to foil a major terror conspiracy involving a plan to carry out a series of blasts across multiple Indian cities.

Delhi Police on Thursday confirmed that the man who carried out the car blast near Red Fort was Dr Umar Un Nabi, after forensic DNA testing matched his biological sample with that of his mother.

While exclusively speaking with ANI, senior police officials said the confirmation came after days of detailed forensic analysis conducted. A senior police officer revealed that after the explosion, Umar's leg was found trapped between the steering wheel and the accelerator of the car, suggesting he was behind the wheel when the car blasted.

'DNA profiling has conclusively identified the deceased as Dr. Umar Un Nabi. His sample was matched with his mother's DNA to establish the relationship,' a senior Delhi Police officer said.

On Wednesday, the DNA samples of Dr Umar's mother and brother were collected and sent to the AIIMS forensic laboratory, where they were matched with the remains of the bodies kept at Lok Nayak Hospital in Delhi.

The explosion in a Hyundai i20 car near the Lal Quila Metro Station in New Delhi on Monday evening claimed the lives of at least 12 people. (ANI)
