The incident on Tuesday came amid claims a woman in Maoro Village was a sorcerer and responsible for the sudden death of a local teacher.
RNZI reports 20 men from East Kwara'ae had demanded compensation and when this was not forthcoming police say they burned down the two traditional houses and looted the properties.
The men have since been arrested.
