Hundreds of travellers were stranded after irate residents blocked the Kapsabet-Eldoret highway in protest against the murder of former Mosop MP Stanley Metto son, Elly Metto.
The protest followed the arrest of Julius Kemboi Kalya after he was linked to the brutal murder of Metto at his home on Thursday.
The residents blocked the busy road using burning tires for the better part of Saturday morning before police officers intervened and opened traffic.
"We are discouraged by the way the police handled the matter. They took long to respond. We have been informed that one of the suspect's relatives is trying to compromise with the police to release Kumutai," Mark Choge, a resident claimed.
It took five hours for the police to arrive at the scene and quell the situation. They then got rid of the bonfires to allow travellers to use the road.
Chesumei Sub-County Police commander Omukolongolo Bosita said the investigation is ongoing and one of the suspects said to be an ex-KDF soldier was adversely linked to the incident and has been detained.
Metto was killed in his house in Kiboswa village, Chesumei, after retiring to sleep just after arriving from Mosoriot centre where he had been drinking with some of his friends.
The suspects trailed him where they attacked the deceased with his wife and made away with valuable items including two television devices, a subwoofer and an unknown amount of money.
One suspect was killed in a mob justice while attempting to escape while the other presented himself to the police in the company of his family members.
"The suspect is now in the police custody, and he will be arraigned in the court on Monday. We are yet to establish more perpetrators and it will be easy to trace those mentioned in the criminal incident," Mr Bosita said.
