Al Falah University, India Gate, Connaught Place, Lodhi Road... the parking near Red Fort - these were among the many places that the prime accused in the Delhi blast case travelled to from October 29 to November 10 before the explosion in the crowded Chandni Chowk area. 

The investigators have used footage from 40 cameras to stitch together the entire route of the accused, Umar Nabi, from the time he entered the university on October 29. 

Calling the Delhi terror blast "painful", Vice President CP Radhakrishnan said that police have to be fortunate every time and terrorists have to be fortunate just once.

On November 10, the blast near the Red Fort complex in the national capital killed 12 people and injured several others.

"Police and the other Intelligence Forces have to be fortunate every time. Terrorists have to be fortunate just once," he said, calling the blast "very painful."

Security agencies are probing three bullet cartridges, two of them live rounds, recovered from the debris near the Red Fort blast site, a source said on Sunday.

The empty shell and two live bullets -- a calibre not permitted for civilian use -- were found close to the burnt Hyundai i20 car, which exploded on November 10 near the iconic Delhi monument, killing 13 people and wounding more than two dozen.

According to the source, the 9mm rounds are generally issued to specialised units or individuals with explicit permission.

"The staff deployed at the spot were also asked to check their issued ammunition, but none was found missing. The cartridges were there, but there was no weapon to fire them. We are trying to understand the entire matter that how the bullets reached the spot," said the source.

In a major breakthrough in the Red Fort area car bomb blast case, the National Investigation Agency (NIA) has arrested a Kashmiri resident who had conspired with the suicide bomber to carry out the terror attack on November 10, said an official on Sunday.

Amir Rashid Ali, in whose name the car involved in the attack was registered, was arrested from Delhi by the NIA, which had launched a massive search operation after taking over the case from Delhi Police, said the official in a statement.

The NIA's investigations had revealed that the accused, a resident of Samboora, Pampore in Jammu and Kashmir, had conspired with the alleged suicide bomber, Umar Un Nabi, to unleash the terror attack.

Amir had come to Delhi to facilitate the purchase of the car, which was eventually used as a vehicle-borne Improvised Explosive Device (IED) to trigger the blast, the statement said.

 In the aftermath of the Red Fort blast that killed 13 people, the central district has intensified anti-terror measures across key stretches of the national capital, carrying out extensive verification drives, enhanced picket checking, and strengthening armed deployment at sensitive spots, an official said on Sunday.

"On Saturday night, teams seized 34 unattended vehicles during a special operation, while 417 challans were issued under the Delhi Police Act in a five-hour checking drive," the officer said.

The security push is part of a broader strategy implemented after the blast, he said.

Former chief minister and president of Peoples Democratic Party (PDP), Mehbooba Mufti, on Sunday cautioned authorities on 'high-handedness' while probing the white collar terror module, citing the example of a father, who tried to immolate himself after his two sons were picked up by police in Kulgam district.

While posting on X, Mufti said, "Bilal Wani an anguished father from Wanpora Qazigund has set himself on fire after his son Jasir Bilal & brother Naveel Wani were detained by the police a few days ago. Petrified about their safety he pleaded with the authorities to just see them which was denied. He has been referred to SMHS Srinagar & is in critical condition. This level of high handedness only deepens wounds and breeds despair. When young men are picked up randomly we risk driving an entire generation into fear, frustration & ultimately towards darker paths."

"Request @JmuKmrPolice to at least allow him to meet the detained members," she further wrote.

The sophisticated 'white-collar' terror module, spearheaded by a group of doctors recently busted by Jammu and Kashmir Police, had been actively scouting for a suicide bomber since last year, with key planner Dr Umar Nabi pushing the agenda, officials said on Sunday.

Interrogation of an arrested co-accused was indicative that Umar, believed to have been killed while driving the explosives-laden car that blew up near the Red Fort on November 10, was a "hardcore radical" and insisted that a suicide bomber was essential for their operations.

Immediately, Srinagar police sent a team to Qazigund in south Kashmir and detained Jasir alias 'Danish', a bachelor in political sciences, on the basis of questioning of the co-accused, including Dr Adeel Rather and Dr Muzzaffar Ganaie.

 A West Bengal resident, currently lodged in the Presidency Jail, is being interrogated by the National Investigation Agency (NIA) in connection with the Delhi car blast attack case, sources said on Sunday.

Sabir Ahmed, a resident of Palashipara's Bara Naldaha in West Bengal's Nadia district, is lodged in the Presidency Jail under the Anti-Narcotics Act.

The security officials, under the state and central directives, have been interrogating Ahmed repeatedly in jail, according to the sources.

Along with this, his brother, Faisal Ahmed, was also taken into custody by the Special Task Force for questioning on Thursday night in connection with the terror network.

Jammu and Kashmir Lieutenant Governor Manoj Sinha on Sunday ruled out any terrorist involvement in the Nowgam Police Station blast, stating that preliminary inputs indicate it was an accident that occurred during sample-collection work.

He said a probe has been ordered to ascertain the exact sequence of events.

Speaking to reporters, LG Sinha said, "There is no terrorist angle in the Nowgam incident. Samples were being taken when this accident happened. I have ordered an inquiry into the matter."

The United Hindu Front on Sunday held protests condemning the terror blast near the Red Fort on November 10, which claimed the lives of 12 people and left several others injured.

A team from the Faridabad Crime Branch brought a young man to Al-Falah University on Sunday as part of ongoing verification exercises linked to the Faridabad terror module. Investigations into the case are still underway.

The terrorist who blew himself up in Delhi had rented a room in Haryana's Nuh shortly before the 10/11 blast, sources said.

The white Hyundai i20 car that exploded near the Red Fort earlier this week was parked at Al Falah University in Faridabad last month, CCTV footage accessed by investigating agencies showed.

Chief Minister Himanta Biswa Sarma has said that one more person has been arrested in Assam for putting up social media posts supporting the Delhi blast, taking the total number of such arrests to 21.

He asserted that no person lending support online to terrorists will be spared.

Sharing the update in an X post late on Saturday evening, Sarma said, "Another anti-national has been arrested by @assampolice, taking the total count to 21."

"We will NOT tolerate anyone expressing support online for terrorists behind the Delhi terror attacks," he added.

Among those arrested, three each are from Kamrup and Bongaigaon, two each from Chirang, Lakhimpur and Barpeta, and one each from Darrang, Goalpara, Nalbari, Hailakandi, Hojai, South Salmara, Kokrajhar, Bajali and Dhubri.

As the probe into the "white collar" terror module widens, the police have detained a medical student at the Government Medical College (GMC) in Jammu and Kashmir's Anantnag.

Security agencies are trying to find out whether Priyanka Sharma, a resident of Haryana's Rohtak, had links with the accused doctors.

According to sources, Delhi bomber Umar had rented a house in Haryana's Nuh shortly before the blast near Red Fort.

Investigations have revealed that Umar stayed for around 10 days in a rented room in Hidayat Colony before the blast.

According to police sources, around 1 am on November 10, Umar left this rented accommodation in his i-20 car carrying explosive materials.

CCTV cameras installed at an ultrasound centre in Nuh captured Umar's car entering the colony.

An extremely volatile explosive, infamously known as the 'Mother of Satan,' was likely used in the blast that ripped through the heart of the national capital a week ago, investigators suspect.

Triacetone triperoxide (TATP) can explode simply due to heat, without any detonator, officials said, with forensic experts now trying to confirm if it was indeed TATP behind the deadly blast.

SP Vaid, the former Director General of Police (DGP) in Jammu and Kashmir, said on Sunday that the Al Falah University (whose doctors have been arrested in the blast case) looked like a hub of terrorism.

"... I was listening to the media that the owner of this Al-Falah University was in jail for three years for fraud. I don't know how such a person can get a license for a university... It is very unfortunate that such a thing was happening, and I am glad that the government has directed the ED and NIA and other agencies to look into its accounts for any foreign funding...," Vaid told the news agency ANI.

"How can a university function without NAAC accreditation?... I am glad that the government is going after such fraudulent universities... Such a university should be immediately closed...," he added.

The National Investigation Agency (NIA) on Sunday morning started carrying out raids in Delhi, Jammu and Kashmir, Punjab, Haryana, Uttar Pradesh and Madhya Pradesh in connection with Monday's explosion near the Red Fort. 

The white coloured Hyundai i20 used in Monday's explosion near the Red Fort entered the Al Falah University on October 29. The car left the university campus on October 30 at around 2.41 pm

Dr Philipp Ackermann, the German Ambassador to India, said on Sunday that the November 10 explosion near the Red Fort was a shocking event. "We were taken by total surprise. I am extremely saddened to see what happened. My heart goes out to those who lost their loved ones, those who are injured. We have been following everything in the news, and it is a terror attack, obviously..," Dr Ackermann told the news agency ANI. 

Officials investigating the Delhi blast have said that the explosive used doesn't require a detonator and can explode simply from heat. According to experts, TATP (Triacetone Triperoxide) is extremely sensitive- friction, pressure or rising temperature can trigger an explosion.

Officials believe Umar Mohammad was aware of how unstable TATP was before he entered the location where the explosion occurred. 

Umar Mohammad, the driver of the Hyundai i20 car that exploded near the Red Fort earlier this week, allegedly received Rs 20 lakh through illegal financial channels as funding, investigations into the terror attack that claimed 13 lives so far have revealed.

Delhi Police sources told NDTV on Sunday that three 9mm caliber cartridges were recovered from the explosion site. Two of these were live cartridges while the third one was an empty shell. It is important to note that 9mm pistols are not allowed to be owned by ordinary people. 

Nearly a week after the explosion near the Red Fort, all gates of the Red Fort Metro Station have been reopened for the public.
