"NIA is investigating the blast in Burdwan and I think real facts will come out after the probe," the governor told reporters here.
West Bengal is a state bordering Bangladesh and it is necessary to be specially alert and take measures to maintain law and order, he said.
The Centre had yesterday decided to hand over to NIA the probe into the bomb blast in Burdwan in which the role of terror groups is suspected.
The Trinamool Congress government, which had said it had faith in the ongoing CID investigation, said the decision was taken suo motu.
It is perhaps for the first time that the Centre has taken a suo motu decision to hand over a probe into a bomb blast case in any part of the country to the National Investigation Agency (NIA) since this premier agency was created in 2008 after the Mumbai terror attack.
Two suspected militants - Shakil Ahmed and Sovan Mandal - were killed and another person Hasan Saheb was injured in the explosion on October 2 in a house at Khagragarh in Burdwan town. Four persons, including two women, have been arrested so far in the case.
