The Bengal police had raided the house - on Badshahi Road - on October 8 after questioning the two women arrested from the house in Khagragarh, where the blast took place.
The house was vacant at the time of the raid - half-a-dozen men living there who claimed to be masons, had decamped. Among those absconding is one Rezaul, suspected to be a key Jihadi element.
But today, the sniffer dogs of the National Investigation Agency (NIA) and the National Security Guards (NSG) found the bombs - bolstering the Opposition claims that the state police are hiding evidence at the behest of the ruling Trinamool Congress.
The BJP's Siddharth Nath Singh, in fact, had 10 questions for the Mamata Banerjee government, including one regarding the "conspiracy" that "forced her government to allow evidence at Burdwan to be destroyed."
Earlier today, the NIA-NSG teams combed a madrasa at Simulia with bomb detectors. They also detained two relatives of the absconding principal Yusuf Sheikh.
During its probe that began on Sunday, the NIA had found material suggesting the madrasa may have been used as a hub by jihadi elements linked to the Burdwan blast. Air gun pellets, sharp-edged weapons, money receipts and jihadi literature - including a Bengali book titled, "How To Die A Good Death" - were found, said sources.
