Police believe Kimilili MP Didmus Barasa escaped to Uganda after a shooting tragedy that left an aide to his rival dead on Election Day.
Police handling the incident said the MP had by Wednesday not surrendered as ordered.
Barasa, who is defending his seat on a UDA ticket, is a licensed gun holder.
The incident involved Barasa and his political rival Brian Khaemba of DAP at Chebukwabi polling station where they were to witness the counting of votes.
Bungoma County Criminal Investigations officer Joseph Ondoro said tragedy happened when an altercation broke out between the two prompting Khaemba to leave and head to his car.
“Barasa followed him in company of four men and ordered them not to allow him (Khaemba) to leave the place. However, Khaemba's driver Joshua Nasokho defied the order and started the vehicle,” Ondoro said.
It was then that Barasa reportedly drew a pistol.
Nasokho was pronounced dead at Kimilili Subcounty Hospital.
Ondoro said they are looking for Barasa for grilling over the incident.
“He has run away but we are looking for him. Let him surrender,” he said.
Ondoro said they launched a man-hunt but they are still combing all possible places Barasa might be hiding.
“We suspect he took a motorcycle towards Uganda but we will get him. He is yet to be arrested,” he said on Wednesday.
The police boss said Barasa knows he is wanted over the incident but chose to switch off his mobile phone and fled.
The area where the incident happened is near the Kenya-Uganda border.
A back up team has been sent to the area to look for the MP.
In Malava constituency, police said they detained MP candidate Seth Panyako and 12 supporters at Maira polling station, over chaos that broke up there.
They were accused of holding election officials hostage before police came to their rescue and took them to Kabras police station.
Police planned to charge them with various charges.
