India's Intelligence Bureau has submitted a report on the Burdwan blast to the country's Home Ministry, blaming West Bengal police for trying to conceal and destroy evidence of the explosions in Burdwan town which killed two on October 2, reports bdnews24.com.
The IB has advised the Home Ministry to entrust the National Investigations Agency (NIA) with the investigations in view of 'prima facie' evidence that the explosions reveal a larger 'trans-regional terror network' involving Jamaat-ul-Mujahideen Bangladesh (JMB), Indian Mujahideen (IM) and Al Jihad, a new outfit with bases in Pakistan.
The IB report said that the two women who were arrested from the house in Burdwan where the explosion took place were both hard core terrorists who were trained in a base in Pakistan's Waziristan province.
"The JMB, IM and Al Jihad are now part of a fraternal terror network that seeks to unsettle South Asia, specially India and Bangladesh," said a senior IB official.
He said Rumi Bibi and Amena Bibi, arrested from the Burdwan house, had joined JMB in Bangladesh ten years ago and had slipped into India along with other activists of the group when they faced a huge crackdown in Bangladesh when Sheikh Hasina assumed power.
Three other women used to work with these two in the Burdwan house that had been turned into a factory for making Improvised Explosive Devices (IED).
"The way they confronted police after the explosions in which their husbands had died proves they were properly trained and motivated, surely indoctrinated," the IB official told the news agency but on condition of anonymity." There were three other women in the team that made the IEDs."
The other three are at large and police are trying to nab them on the basis of description now available from neighbours.
Two other hideouts in Burdwan town have been raided and documents have been seized from one person who has been arrested.
"SIM cards seized from those nabbed suggest long distance calls were made to locations in Kashmir, Mumbai, Dhaka, Chittagong and Chennai. This is clearly pointing to a larger South Asian operation and one not restricted to India," said the IB official.
Al Jihad is a new terror affiliate of the ISIS of Middle East and it is seeking to spot, train and arm recruits for operations in South Asia but many of whom may ultimately be taken to fight the jihad in Iraq and Syria, core areas of the ISIS operations.
