The high intensity bomb blast in a residential locality in Patna on Monday night has put the city on high alert as there is a suspicion that the timer-run explosives were being made for a terror attack.
A National Investigation Agency, NIA, team is likely to vist the spot on Tuesday to carry further investigations.
SSP, Patna, Jitendra Rana confirmed that NIA had got in touch with him and sought details of the blasts.
The incident took place at around 11 pm on Monday night at a government MIG building in sector 3 of Bahadurpur locality under Agam Kuan police station.
Police had recovered three live bombs while two residents in the flat, Kundan amd Hemant, managed to escape soon after the explosion. The bombs were later diffused.
"The bombs, having a timer with lotus shaped watches, are similiar to the explosives used in Gandhi Maidan serial blasts and Bodh Gaya blasts. We are trying to identify the criminals. We cannot rule out the terror angle," said a senior police officer.
Police have started investigating the case from all angles with the link of Maoists also being probed.
