The NIA officers were questioning the mysterious Burdwan blast victims in Kolkata and another team was interrogating three suspects - including an alleged ISI conduit - in Chennai after the agency found uncanny similarities in the IEDs that exploded in.
With new updates popping up in the Burdwan blast case probe, National Investigation Agency is questioning three suspects at Park Circus nursing home. The suspects were admitted here by Burdwan Police on October 6. All three reportedly have blast injuries, reported media.
NIA is probing if the trio is linked to the October 2 Burdwan blast - the agency's suspicions heightened by the suspects' contradictory claims.
In a press release, NIA claimed that it conducted searches at various places, including the rented residence of Shakil Ahmed Gazi in Beldanga, Murshidabad. Gazi, killed in the blast, was said to be the No. 2 in the Jamaat-ul-Mujahideen Bangladesh (JMB) module in India.
"Certain incriminating documents and metal pieces used in making IEDs have been recovered. The NIA team also initiated a thorough search of the Simulia Madrassa. Based on preliminary investigation, three persons were summoned in Chennai for questioning by NIA."
The NIA is also probing as to why the "suspects" were taken to a private nursing home, while Abdul Hakim - who was injured in the Burdwan blast - was admitted to the state-run SSKM Hospital.
In the Chennai blast, low-intensity IEDs were set off in two sleeper coaches, killing a software engineer and injuring 14 passengers on May 1.
