Two days after the 10 multiple coordinated explosions, the four people were picked up by the National Investigation Agency(NIA) in Patna after police claimed they had checked out of a hotel near the Mahabodhi temple complex at about 6.30 AM, just about two hours ater they checked in.
No arrests have been made in the case yet. The first blast took place at the temple at about 5.30 AM followed by nine successive explosions in a near simultaneous operation. A police officer said the four people were picked up in the Bihar capital and being questioned at an unknown location there.
The identity of the four were immediately not known. Police said that Binod Kumar Mistri, who has been detained by the NIA on the basis of his voter I-card found inside the temple during search after the Sunday explosions, continued to remain under custody.
Police, however, were not able to ascertain his role, if any, in the attack on Buddhism's holiest shrine. Union Home Ministry officials said the probe into the multiple blasts will be handed over to the NIA. A formal order entrusting the NIA with the investigation will be issued very soon, the officials said in New Delhi.
Bodh Gaya Temple Management Committee(BTMC) member Arvind Singh told PTI that CRPF and Bihar Military Police (BMP) have taken over charge of security at the historic temple.
BTMC private security guards are assisting them inside the temple. Visitors are allowed inside the temple only after proper frisking, he said.
The BTMC member said that there is no let up in enthuasism of visitors to the temple. With no leads coming from the footage from 15 CCTV cameras that the investigators are poring through, police suspect it is possible that the attackers may have evaded those cameras.
The footage is also stated to be of poor quality making it difficult to capture the images of people caught on the cameras.
The Gaya district administration also imposed restrictions around the Mahabodhi temple under Section 144 CrPC and ordered several shopkeepers in the area to close down. The preliminary probe has found a timer device and traces of ammonium nitrate similar to that used by modules of banned terror outfit Indian Mujahideen(IM) in some previous attacks in the country.
