The probe was handed over to the National Investigating Agency (NIA) by the Tamil Nadu Police so that the complete conspiracy hatched overseas including in Sri Lanka and Malaysia could be unravelled, official sources said here today.
Besides these two countries, a probe would also be carried out in Maldives from where the suicide attackers were supposed to take a boat ride to reach a coast in Kerala, the sources said.
In a related development, Interpol has issued a Red Corner Notice against Mohamed Hussain Mohamed Sulaiman, another accused arrested in Malaysia in connection with the hatching of this conspiracy.
47-year-old Sulaiman is wanted in India for alleged hatching of "criminal conspiracy, acts done by several persons in furtherance of common intention, possession of forged or counterfeit currency-notes or bank-notes, terrorist act and raising funds for terrorist act".
India has already approached the Malaysian authorities for extraditing Sulaiman to find out other details of the terror plot and also the identity of the two suicide attackers who were supposed to set sail from Maldives.
The terror plot was foiled by an effective coordination of Intelligence Bureau(IB) with foreign countries as Malaysia tipped the central agency about an alleged conspiracy being hatched from Sri Lanka about carrying an attack on US and Israeli consulates in Chennai and Bangalore.
