As per the NIA, terrorists have used this tunnel to escape and also for supply of arms and ammunition.
A few days ago, some women from Madarsas were arrested in connection with Burdwan blast. Now the the discovery of secret tunnels beneath has stirred up further possibilities.
The nearby pond, where the tunnels end, is suspected to be the spot where a number of documents may have been dumped by the terrorists while they escaped.
As per a TOI report, "The huge amount of literature written in Arabic and Urdu found in the madrassa also indicates the kind of 'classes' run by the leaders.
The NIA team also led a search in the nearby ponds suspecting that the terrorists dumped some of the important documents in them while fleeing. The team questioned the two members of the CID bomb disposal squad who destroyed the IEDs."
After the police went searching for the registration of the Madarsas and its verification, they discovered that only 36 out of 700 Madarsas in Burdwan district were registered.
As per an NDTV report, "The madrasa came under the scanner after the two women arrested for the Burdwan blast allegedly admitted their links with it... As many as 30-40 young girls lived with teachers and their husbands at the madrasa, located 40 km from Burdwan town, say locals."
"They had no links with the village, all the people here were outsiders. They wouldn't talk to us," Bashir Hussain, a villager was quoted as saying in NDTV report.
