Serial blasts rocked relief camps in the riot-hit Kandhamal district triggering panic among the inmates living in those shelters since violence erupted in the area, but no casualty was reported.
The bombs, suspected to be hand-made ones of low intensity, went off in Nuagaon, Mahasinghi village and Baliguda town at 7 pm, 8 pm and 9 pm respectively on Sunday night, the police said on Monday.
As the first blast occurred near a relief camp, the inmates ran helter skelter in search of safety.
"Since they have been successful in exploding bombs near the heavily guarded relief camp, there is no guarantee that the explosion will not take place in another camps," said an inmate.
Senior police officials in charge of security, however, were yet to ascertain who executed the explosions.
Since the blasts took place at regular intervals, it seemed to be a planned step to create panic among the people, a senior official said.
When contacted, Deputy Inspector General, southern range, R S Koche said the police was investigating into the matter.
