Holding the Centre responsible for Burdwan blast, Trinamool Congress (TMC) leader and West Bengal Education Minister Partha Chatterjee on Saturday said the government sitting in New Delhi is not serious and competent enough to depute border guards and that is why illegal migrants are intruding in the state.
"We are raising questions whether there has been any shoddy job in guarding the borders. They are coming and going, selling bombs and doing different things. Who are they? Where is the incompetence? The Union Government must answer this," said Chatterjee.
The TMC leader also alleged that the Bharatiya Janata Party (BJP) and the Communist Party of India-Marxist (CPI-M) are disrupting the peaceful situation in the state to reap political benefits.
The National Investigation Agency (NIA) is also assisting the state police in investigating the case.
Two suspected militants were killed and one sustained injuries in an explosion at a TMC leader's house in Burdwan town on October 2.
Two women were arrested in connection with the explosion on October 5. The police are probing the possible involvement of militant outfits like Lashkar-e-Toiba and Harkat-ul Jihad al-Islami in the blast.
A large number of watch dials, SIM cards, and other tools required to make improvised explosive devices were found in the house where blast took place during the festival of Durga Puja.
