Itanagar: At least 29 houses were allegedly set on fire at Tezu Kholla in Lohit district by unidentified persons.
However, there was no report of any loss of life in the arson which took place on Saturday night.
The occupants were mostly daily wage earners, rickshaw pullers and fishermen from Bihar.
Most of the houses were empty at the time of the incident as the occupants had already left for their native villages in Bihar after the end of the election, an official report said here today.
Some of the occupants, who were sleeping in their houses on that fateful night, have somehow managed to escape from the inferno, the report said.
Senior Congress leader Kalikho Pul visited the accident site from Anjaw yesterday and took stock of the situation.
Pul urged the Lohit Deputy Commissioner to investigate the matter immediately and arrest the perpetrators of the incident and punish them as per law.
