Mourners suspected the six to be behind the murder of the businessman.
Mr Narengo, who condemned the incident, said a number of mourners have recorded statements at Busia Police Station.
The businessman was shot by three assailants in his house at Masabule village on November 1.
Angry mourners lynched six people at a funeral of a prominent businessman at Masebula village in Busia County on Friday.
The six were said to be among a group of ten hired men at the funeral of Johanes Okoth who was shot dead two weeks ago by unknown assailants.
A group of boda boda riders pounced on the six who were dressed in black after they failed to identify themselves.
“Ten people dressed in black suits were in the funeral procession from Sega Mission Hospital mortuary. When we asked them to introduce themselves they declined,” said Ms Roselyne Aduol, a sister to the late business man.
“Soon, angry mourners descended on them with crude weapons, killing six of them,” added Ms Aduol.
It was later discovered that the ten were bouncers from Kisumu who had been hired by a close relative of the slain businessman.
