The Mumbai Police are currently probing the involvement of two lesser-known outfits - the Gujarat Revenge Group and Tableeq - in the serial blasts. Intelligence sources here confirmed that names of the two outfits came up during investigations.
While the Gujarat Revenge Group is said to be involved in subversive activities in Gujarat and Maharashtra, the Tableeq is primarily managed by ex-cadre of banned outfit SIMI.
The police have launched a massive hunt for two key members of the groups - Riaz of the Gujarat Revenge Group and Imtiaz Batkal, who was a key member of SIMI and is now believed to be working for Tableeq.
Sources confirmed Riaz and Imtiaz Batkal’s names have figured "prominently" in investigations.
"The duo seems to be involved in providing logistics to the group that carried out the explosions. They would have provided a safe hideout for storing the explosives and subsequently assembling the bombs," a source said.
It has also been revealed during investigations that the use of cell phones by the militants was kept to a minimum. Instead, they relied more on the use of e-mails.
The intelligence agencies have cracked at least five e-mail accounts which given some leads on the conspiracy. The Mumbai Police has been directed to identify the computers from which these e-mails originated using the "footprint technology". It has been revealed that e-mail were sent from different cyber cafes.
Meanwhile, intelligence agencies have reiterated that the Mumbai serial blast were linked to the recent seizure of weapons in Aurangabad, Malegaon and Bheed. A Tata Sumo vehicle carrying a consignment of weapons had escaped the police following which the Mumbai Police was put on alert.
Intelligence sources said a massive hunt is on to trace local contacts of Riaz and Batkal in the Nasik districts.
Meanwhile, PTI adds from Kathmandu, Aftar Moiddin Siddiqui and Gulam Hussain Cheema - the two Pakistani nationals arrested in connection with a five-year-old RDX seizure case and being investigated for possible links with the Mumbai blasts - were remanded to five days of judicial custody by a Nepalese court on Friday.
