"A detailed report is being sent to the Union Home Ministry. All aspects are being looked into - whether there was link with any terrorist organisation behind the incident," Reddy told reporters after a high-level meeting at 'Nabanna', the new state secretariat.
Chief Secretary Sanjay Mitra, Home Secretary Basudeb Banerjee, the DGP and the ADG-CID Ramphal Pawar were present at the meeting.
BJP has demanded that West Bengal government hand over the blast probe to NIA. Its national secretary Siddharth Nath Singh had yesterday said that the Centre would put pressure on the state as the case had international ramifications.
He had also charged the state government with destroying the evidence and not handing it over to NIA for a probe. Countering the demands, Trinamool Congress accused BJP of politicising the issue and stoking communal tension in every state.
It also made a scathing attack on Prime Minister Narendra Modi for not trusting the state administration in probing the incident which has suspected terror links.
One suspected terrorist who was injured in the explosion at Khagragarh in Burdwan was today arrested taking the total number of those apprehended by the police in the case to four.
