Police in Kisii are hunting for a group that allegedly beat a man to death in Nyatieko village.
The man identified as Justus Omoni, 48, was found dead after a suspected assault by a group of community policing group.
The group had intervened in a domestic quarrel between Omoni and his wife over an erected structure in their compound.

His family picked him from the scene and brought him to the house where he died.
