"We witness the emergence of a Hindu militant who also died in the blast," Babar told BBC Bangla Service yesterday, referring to the Netrakona suicide bomber as Yadav Biswas.

Wire was tied around his whole body and the evidence of the bombings showed he was a JMB man and Hindu, said the minister, adding, "The JMB has been speaking about an ideology. But now it is a new dimension. We need to look into it well."

At a press briefing at the home ministry's conference room yesterday, Home Ministry Additional Secretary Md Mohsin also said a suicide bomber named Yadav Biswas conducted the bomb attack in Netrakona yesterday morning.

While the suicide bomb attacks have so far been directed mainly to the judges and lawyers, now the criminals have attacked the common people, Chief of the ministry's Media Cell Khandakar Manirul Alam said.

The cycle repairing shop where the suspected suicide bomber worked has confirmed his name as Yadav Biswas, he added.

He informed newsmen that since the August 17 countrywide bomb blasts 181 cases have been lodged in connection with bomb attacks, and charge sheet of 72 cases and final investigation report (FIR) of six of them have been submitted.

About 700 suspects have been netted and 103 cases are still under investigation, he said.

Meanwhile, Yadav Biswas' elder brother Biplob told our correspondent that Yadav went to the spot to see a bomb that was found there earlier.
