The CBI on Thursday took over investigation of the October 30 serial bomb blast cases in Assam, in which 89 people were killed and more than 500 were injured. This followed the failure of the Special Investigation Team (SIT), which had been constituted by the state Government, to make any headway in the case despite arresting 11 persons.
In a notification issued on Thursday, the Centre said the decision to entrust the CBI with the investigation was taken in consultation with the state Government.
A team of 30 CBI officials will leave for Guwahati on Friday to take over the case.
This is the second time that the CBI will be investigating a bomb blast in Assam. It had investigated the death of Nagen Sharma, then minister of Forest and PWD, and others, in a bomb blast in 2001.
