Panaji, May 26 (IANS) Members of the Hindu rightwing group Sanatan Sanstha (SS), accused of carrying out the 2009 Diwali eve blast in Goa, ‘Googled’ circuit diagrams from the internet and later used them to build improvised explosive devices (IED), National Investigation Agency (NIA) officials said.

‘In furtherance of the said conspiracy, accused Dhananjay Ashtekar downloaded circuit diagrams using the internet (Google search),’ NIA officials said in their chargesheet which was submitted to a local court last week.

The chargesheet accuses 11 people (all members of the SS) of carrying out the 2009 Oct 16 blast, in which two SS members were killed when the detonator rigged gelatin sticks they were ferrying by scooter to Margao, 35 km here, accidentally exploded.
