Security officials had to travel more than two hours throughout thick forests and rubber plantations on the mountain before reaching the house.
The raid at the house was conducted after Sof Tohluenoh, 38, believed to be a chief of RKK insurgent group, was shot dead during a fight with security officials on October 15. It was believed his members were gathering to work out a plan to take revenge on the authorities.
However, when the forces reached the house, the alleged RKK members had already fled.
Police refused to reveal the names of the suspects.
