National Investigation Agency (NIA) has said that the prime accused in Margao blast, Malgonda Patil stayed in the saints quarter, 'Sant Kakshay', at Sanatan Sanstha's Ramnathi Ashram in Goa.
Patil, who died in the blast, stayed next to the Sanstha founder Jayant Balaji Athwale, the NIA said.
"Malgonda Patil was an active member of Sanatan Sanstha involved in the publicity of Sanstha and used to hold satsang (meetings) at various places and stayed in Abhyasika/Sant Kakshay of Sanatan Sanstha Ashram building in Ponda," the NIA said in its chargesheet.
The right wing Hindu organisation, Sanatan Sanstha, had initially distanced itself from all the accused in the Margao blast. NIA filed the chargesheet on May 17 in south Goa district court, a copy of which is with PTI.
Malgonda Patil, who died while ferrying the explosives in Margao, was Managing Trustee of Dharma Prachar Sabha, a trust of Sanatan Sanstha.
NIA has also found that Malgonda Patil and another accused Dhananjay Ashtekar hatched the blast conspiracy at former's room close to the room of Jayant Balaji Athawle, on the first floor of the Ashram, during June 2009, four months before the blast.
Investigators have found that Margao blast was just a loop in the serial blast planned at five different places across Goa on October 16, 2009.
