State House secretary digital in the communications department Dennis Itumbi on Wednesday evening arrested by detectives from the Director of Criminal Investigation (DCI).
He was picked up at a restaurant in Nairobi and taken to the DCI headquarters for questioning.
His arrest comes days after the police revealed that they were narrowing down on suspects of the fake letter to assassinate Deputy President William Ruto.
