(MENAFN- Kashmir Observer) New Delhi ~ The National Investigation Agency (NIA) has released four individuals, including three doctors, after finding no evidence linking them to the Delhi blast conspiracy.

Their release has shifted the focus of the widening probe, which continues to uncover alleged links between medical professionals and what investigators describe as a“white-coat” terror module operating across multiple states.

The four, Dr Rehan, Dr Mohammad, Dr Mustaqeem and fertiliser dealer Dinesh Singla, were picked up from Haryana's Nuh in recent days for suspected links to the blast that killed 13 people on November 10.

According to India Today, officials said that despite intensive questioning and searches, investigators found“no concrete link” between them and the key accused, Dr Umar Un Nabi, a Pulwama-based medical professional associated with Al-Falah University.

Authorities had also probed whether explosive chemicals were sourced through fertiliser dealers, but a lack of digital or material evidence led to their release. Families of the detained men confirmed they were allowed to return home, though the NIA will continue to monitor them.

Seven people from the Mewat belt had been detained earlier, but with four now released, investigators are reassessing the trail based on abandoned phones and CCTV footage.

MD Student in Kashmir Detained, Questioned and Released

As the focus widens, a female doctor pursuing her MD at Government Medical College, Anantnag, was detained for several hours for questioning after her name surfaced during the interrogation of a former college staffer. Police seized her phone and SIM card for forensic analysis before releasing her the same night.

Her family, according to the Hindustan Times, has denied any terror links, saying she merely knew Dr Umar as her senior in the same department. They termed reports about her living in private accommodation as“false”, insisting she stayed in the college hostel.

UP ATS Scrutinises 200 Kashmiri-Origin Medicos

Leads emerging from Kashmir have prompted the Uttar Pradesh Anti-Terrorism Squad to verify the records of nearly 200 Kashmiri-origin medical students and doctors studying or posted across UP. Colleges in Lucknow, Meerut, Kanpur, Saharanpur and other cities have been contacted as part of the screening, amid concerns about a larger network of highly educated operatives.

Delhi Court Sends Youth to NIA Custody

Even as some detainees are being cleared of suspicion, the probe has tightened around others.

A Delhi court on Tuesday granted 10 days' NIA custody to Jasir Bilal Wani. Jasir, a 20-year-old college student from Qazigund, Kashmir, has been described by NIA as an“active co-conspirator” who allegedly assisted suicide bomber Dr Umar by modifying drones and attempting to develop rockets.

Jasir and his uncle, Nabeel Ahmad, were picked up by the Jammu and Kashmir Police a few days back during the ongoing investigation.

In a tragic turn, Jasir's father-who reportedly set himself on fire after his son's detention-succumbed to his injuries at a Srinagar hospital on Monday.
