Migori governor Okoth Obado will spend the weekend in police custody as the probe into Sharon Otieno’s murder continues.
Police said the governor will be charged in a Nairobi court on Monday as a person of interest in the Rongo university student’s killing.
He was grilled for hours by officers from the Directorate of Criminal Investigations at the Kiambu headquarters.
The county chief has denied any link to the murder of the 26-year-old student but admitted they were lovers.
Last week, Obado told the police in Kisumu that he too was interested in knowing Sharon’s killers.
