"The ISI is providing financial and logistical support to outfits like Babbar Khalsa International (BKI) and were using Tunda's network to this end," said a senior police officer.
The police claimed Tunda, who is currently in four days' police custody, stated during interrogation that he had placed 10 kg explosives near Hindu Dhaba in Amritsar in December 2009. The Punjab Police, however, were able to recover the explosives. Three people were arrested in this case.
The police had claimed that the consignment of explosives was procured and delivered to Ambala by Lashkar-e-Toiba (LeT) operatives who were then supposed to hand it over to BKI members before smuggling it into the capital.
On October 13, 2011, a stolen TATA Indica laden with RDX was recovered at the Ambala Cantonment railway station. "The explosives had been brought from Pakistan through Nepal. Tunda's involvement has also surfaced in 21 terror bombing cases of Delhi between 1993 and 1998."
"While the previous phase (of Sikh militancy) involved helping to organize and consolidate amateur Islamist outfits, since such outfits have more or less served their purpose for close to half a decade, now the ISI's main aim is to resurrect Sikh militancy in the country," said the officer.
