Patna, Jun 10 (IANS): Facing criticism over the explosion in a madarsa, Banka Superintendent of Police Arvind Kumar Gupta said the explosion happened due to a crude bomb kept in a container.

The officer said no terror angle appeared during the investigation.

"We have seized Rs 1.65 lakh from the cupboard of Maulana Abdul Momin who died in the blast on Tuesday. Besides that there was no evidence to prove a terror angle in this matter. There is no evidence of an IED in the debris as well," Gupta said.

The officer added that the bomb was not so powerful.

The claim of the officer was quite astonishing keeping in view that a huge portion of the madarsa building collapsed in the explosion.

Suharsha Bhagat, district magistrate of Banka, said that the madarsa was not registered with the education department. It was built on private land.

Meanwhile, sources said that the National Investigation Agency also made inquiries with the district administration and took a copy of the FIR filed in the case.
