Matungu Member of Parliament Justus Murunga has been arrested in Kakamega after the police gave him 6 hours to surrender to the Police.
Murunga becomes the fourth politician to be arrested in just under 24 hours over alleged links to the killings in Kakamega County.
Politicians Cleophas Malala (Kakamega Senator), Rashid Echesa (former Sports Cabinet Secretary) and Libinus Oduor (Mayoni MCA) were on Friday questioned by police on the activities of criminal gangs in Matungu.
Investigations have followed a rise in insecurity in the sub-county, where more than 10 people have died in one month.
Mr Malala was arrested at Sovereign Hotel in Kisumu by officers who reportedly arrived in two vehicles.
He tried to protest but was apprehended and taken to the Nyanza Regional Police Headquarters for questioning.
Mr Rashid Echesa was arrested immediately after attending a meeting with The Deputy President William Ruto.
Mr Oduor, who had been summoned to record a statement on the issue, also presented himself to police.
