A 73-year-old man is being held by the police for killing his son at their home in Cherangany's Chepsiro location, Trans-Nzoia on Sunday evening.
James Tarus is said to have strangled his 31-year-old son to death for disrupting his evening sleep.
The Directorate of Criminal Investigations (DCI) said that the son who returned home four years after going missing is said to have gone to the suspect's bedroom where he was asleep and started disrupting his sleep by jolting and shaking the bed.
At the time, the deceased is said to have been under the influence of alcohol.
"The victim who has been away from home for four years found his elderly father enjoying an early evening power nap in his bedroom.
"At his father's room, he jolted him to wake as he lifted the bed. Angered by his son's actions, the old man whacked his head using a nearby wooded bar before tying his rope around his neck and restraining him to a sofa," the DCI said.
Neighbours who were alarmed by the commotion from the suspect's house could not save the young man's life because, by the time they arrived at the scene, he was already dead.
"Cherangany police officers who rushed to the scene arrested the suspect before escorting him to the station where he is being held as the investigations continue," the DCI added.
