A mob tried to attack Chief Minister N Biren Singh's empty ancestral house on Thursday night, despite a security clampdown and curfew in the Imphal valley.
Security forces, however, were successful in foiling the attempt after firing in the air.
Nobody stays in the CM's ancestral house
Singh lives in a separate, well-guarded official residence in the centre of the state's capital.
"There was an attempt to attack the chief minister's ancestral house at Heingang locality in Imphal. Security forces stopped the mob around 100-150 metres away from the house," a police officer said.
Nobody stays in the house now though it too is guarded round the clock, the officer said.
Two groups tried to attack from different directions
The police officer said, "Two groups of people came from different directions and approached the CM's ancestral residence but they were stopped."
Several rounds of tear gas shells were fired by RAF and state police personnel to disperse the mob.
The authorities switched off the electricity connection in the entire area to help reduce the visibility of the protestors. More barricades were added to the previous ones near the house.
The protestors also burnt tyres in the middle of the nearby road.
Ambulances were seen advancing near the spot but till now there is no report of injury to any side.
