Narok Senator Ledama ole Kina will be arraigned next week on hate speech and ethnic contempt charges.
The fiery senator was picked up by detectives from the Directorate of Criminal Investigations (DCI) as he left Royal Media Services studios on Lenana Road, Nairobi, Tuesday. He was driven to the Kilimani Police Station for questioning.
The National Cohesion and Integration Commission (NCIC) immediately confirmed it was behind the senator's arrest.
NCIC accused Ledama of making inciteful utterances on February 19 on national television.
"The invective and diatribe utterances have caused animosity and triggered tension among the different communities living in Narok.
Peace has been destabilised as a result of these reckless utterances and therefore Hon Ledama will be held responsible," NCIC chairman Samuel Kobia said in a statement.
"We shall not tolerate these kind of utterances that are diving Kenyans along ethnic and tribal lines. Any leader regardless of their political affiliation or station in life will be held accountable for their own actions," added Dr Kobia.
