Officials in the southern Mexican state of Chiapas say at least four indigenous people were killed and five injured when a group of men attacked a house in the town of Chamula.
Local officials say one of the men killed was known in the area as a sorcerer.
The gang forced their way into the house at night and hung a man accused of practising voodoo; the others were shot.
The police say they have arrested a man linked to the attack.
