DCI George Kinoti said they want Barasa to shed light on the death of Brian Olunga, his rival's aide.
He is alleged to have shot him on the forehead killing him on the spot on August 8, at Chebukwabi in Kimilili, Bungoma county.
“A specialized team of sleuths based from the elite Crime Research & Intelligence Bureau and the Homicide department has been dispatched to augment the teams on the ground for his manhunt,” Kinoti said.
“Serious action will be taken against any person/s found to be harbouring the murder suspect.”
On Wednesday, the DPP issued a warrant of arrest against Barasa.
The MP reportedly shot and killed Brian Olunga on August 9.
Olunga was a bodyguard to Brian Khaemba, who was Barasa's opponent in the Kimilili parliamentary race.
