(MENAFN- IANS) New Delhi, Nov 26 (IANS) The National Investigation Agency (NIA) was granted a 10-day custody of Soyab, the accused in the Delhi terror blast case, who was arrested in Faridabad earlier on Wednesday.

Soyab was presented before the Patiala House Court, which approved his transfer to NIA custody for 10 days.

Additionally, another key accused, Aamir Rashid Ali, had his NIA custody expiring on the same day. He was also presented before the court, which extended his custody by an additional seven days.

The NIA, earlier in the day, arrested Soyab, a resident of Faridabad's Dhoj, for harbouring terrorist Dr Umar Muhammad, also known as Umar Un Nabi, immediately before the Delhi terror bomb blast.

Soyab is the seventh person to be arrested in connection with the case.

According to the NIA, he not only harboured Umar before the attack but also provided logistical support crucial to the execution of the November 10 car bombing near the Red Fort that killed several people and left many others injured.

Before this arrest, the NIA had taken six of Umar's close aides into custody as part of ongoing investigations under case number RC-21/2025/NIA/DLI.

The NIA stated that it is actively pursuing multiple leads related to the suicide bombing and has been conducting coordinated searches across several states with the assistance of local police forces. The agency said its objective is to identify and apprehend all members linked to the larger terror network responsible for the attack.

Meanwhile, ongoing investigations have revealed chilling details about terrorist Umar's methods and preparations.

According to interrogation inputs from arrested members of the terror module, Umar maintained what investigators describe as a "mobile workstation" -- a large suitcase containing bomb-making tools, chemical compounds and containers. He carried it with him wherever he went.

Umar, a medical professional associated with Al-Falah University in Faridabad, reportedly conducted chemical tests in his room on campus before creating the final Improvised Explosive Device (IED).

One of the arrested suspects, Dr Muzamil Shakeel, also affiliated with the same university, confirmed to interrogators that Umar experimented with substances that were later used in the blast.
