The probe into the multiple blasts in Bodhgaya, Bihar, will be handed over to the National Investigation Agency (NIA).
A formal order entrusting the NIA with the investigation will be issued very soon, home ministry officials said.
A team of NIA had reached Bodhgaya Sunday evening, hours after the temple town was hit by the terror attack, and is assisting the Bihar police in the investigation.
The five-member NIA team, comprising a DIG, two SPs and two others, has collected evidence and forensic materials from the site and is working on various clues.
Bihar chief minister Nitish Kumar too had asked the Centre to hand over the investigation into the Bodhgaya blast to NIA.
