Two cases were registered in Bihar in connection with the October 27 serial blasts - one at GRP Patna and another at Gandhi Maidan. While the first was handed over to the central agency two days ago, the second was given to it today.
"There is no doubt on it," Abhayanand told at a press conference when asked whether the involvement of IM in the Patna and Bodh Gaya blasts were confirmed.
"The circumstantial evidence leading to his death suggests that he was not a human bomb but erred while setting the timer while strapping two bombs in his waist," he said.
Referring to the link between Patna and Bodh Gaya blasts in July, Abhyanand said lotus brand watches used in both places have been recovered from a lodge at Ormanjhi in the outskirts of Ranchi.
"Though the watches are from separate batches but of similar make," he said adding about 25-30 gelatin sticks and 14 detonators were also seized from Mohammad Mojbullah Ansari during raids at his Ormanjhi lodge.
