Tiaty MP William Kamket has been arrested over the banditry attacks in Kapedo that have left at least seven people dead.
The legislator's arrest came a day after six people were murdered and dumped in a remote village in Baringo County.
The KANU lawmaker was apprehended by detectives in Nairobi County on Thursday, January 21.
Reports stated that he was detained at Kileleshwa Police Station.
Police said that they will transfer him to Nakuru County for further investigations.
Kamket was accused of inciting local citizens to revolt. The issue is facing a number of challenges, from land and boundary cases to civil wars among various communities.
"The case in court revolving around boundaries ascertained that Kapedo is in Tiaty and Baringo. We shall face off with anyone who wants to oppose the decision by the court, the Senate and the will of the people," Kamket said.
The MP, on Wednesday, January 20, joined a section of leaders from Baringo and West Pokot and appealed to President Uhuru Kenyatta to deescalate the ongoing security operation in the area.
Majority leader Samuel Poghisio and Kamket accused the security operators of using excessive force to disarm residents.
While addressing the media on Tuesday, January 19, Interior CS Fred Matiang'i warned that operations in the area would proceed until individuals propagating the banditry attacks were accosted.
"We are going to act decisively. We are going to make sure that those involved are facilitated to meet with the law. By the time we are done, it will be a story to be told to the generations to come.
"I am asking those who know those who murdered our senior police officer to bring to surrender them. We will go for them no matter how long it will take us," Matiang'i said.
Rift Valley Regional Commissioner, George Natembeya, added that police were also disarming locals who possessed illegal firearms.
Law enforcers were also ordered to flush out criminals.
