The CBI has reopened investigations into the 2006 Nanded blast, which is being seen as a key indicator of a Hindutva group's involvement in terror activities.
The CBI also took custody of Rakesh Dhawde, one of the accused in the September 29 Malegaon blast even as the probe agency claimed that he had provided arms training to those allegedly involved in the Nanded incident.
The decision to reopen the case was taken after some leads emerged during the investigations into the Malegaon case in which 11 people, including Lt Col Shrikant Purohit, have been arrested.
"We have reopened the Nanded investigations," CBI Director Ashwani Kumar told PTI today in New Delhi.
Dhawde has been remanded in CBI custody for three days, a senior CBI officer said, adding, if need arises, they would move court to take custody of others also.
The CBI had charge-sheeted ten people in the Nanded case. But sources said it has not been able to trace the leads, as yet, provided by some of the accused who claimed to have admitted, before investigators, their role in the earlier cases.
The CBI would also try and probe the links of those arrested in the Malegaon case including Lt Colonel Purohit, with the Nanded case.
Earlier, CBI's role had come into question from the probe conducted by central security agencies and Maharashtra's ATS as the agency appeared to have not taken due cognisance of deposition of one of the accused arrested in the Nanded case.
The accused, whose voice had to be restored by operating his vocal chord which was damaged in the blast, had told investigators that Naresh Rajkondwar, a Bajrang Dal activist, had allegedly planned three blasts outside mosques that shook Jalna and Parbani in Maharashtra in 2003 and 2004.
