The arrested key suspect in Burdwan blast is believed to have linked to a plot to assassinate Prime Minister Sheikh Hasina and stage a coup in Bangladesh, India's top security agency disclosed on Sunday.
The National Investigation Agency (NIA) sleuths probing the Burdwan blast has said that a key suspect identified as Shahnur Alam has accepted chalking out a plan to assassinate Sheikh Hasina.
Sahanur Alam alias Doctor, arrested in a village in the Northeastern State of Assam on Friday night, is an operative of banned Jamaat-ul-Mujahideen, Bangladesh (JMB) also active in Eastern India.
During police interrogation, Alam has confessed to the assassination plot and has also revealed many other secret information regarding the matter.
Bangladesh security agencies are seeking the latest revelations from NIA, an official told The Daily Observer.
The accidental blast took place on October 2, inside a residence in Khagragarh, Burdwan killing two JMB militants and injuring another. Probing the blast, the NIA has arrested several people including Bangladesh nationals, while Bangladesh detectives arrested two other suspects in connection with the blast.
The JMB operatives are presently running sleeping cells in Assam and West Bengal after a crackdown by Bangladesh anti-terrorism unit of Rapid Action Battalion (RAB) which caused them spill-over into neighbouring states of India.
Alam, 36, had been on the run since October 2, when two members of the JMB were killed in an explosion while making improvised explosive device (IED) in Burdwan, West Bengal.
Shahanur is a motivational trainer of terror outfit JMB and was arrested by the NIA with the help of state police.
The Bangladeshi terror outfit was preparing IEDs to be transported to Bangladesh for possible terror attack here.
The suspect contradicted police statement and told reporters outside the court that he had surrendered to police.
Assam's Director General of Police Khagen Sharma disagreed and stated: "Jihadis are not allowed to surrender. He was arrested."
Shahnur's wife, 36, was earlier arrested in Guwahati on November 8 on the same charges as her husband.
It was presumed that JMB was lying low since authorities cracked down on it after it detonated nearly 500 bombs almost simultaneously on one day in 2005 across Bangladesh, including in the capital Dhaka.
