Early last week, police officers investigating the gruesome murder of Monica Kimani were treating renowned Citizen Television journalist Jacque Maribe as a witness.
Tables turned later in the week following a grilling session that Maribe was subjected to at her house and the Directorate of Criminal Investigations (DCI) headquarters with sleuths now viewing her as a suspect.
She was arrested on Friday and is expected to be arraigned in court today, Monday.
It is not clear the charges that the police intend to press against her.
According to the police, Joseph Irungu visited the slain Monica Kimani riding in Maribe's vehicle and would later shoot himself in the journalist's bedroom.
Mr Irungu claims that the gunshot wound he sustained was caused by a shot fired by criminals, a contention that the police have refuted.
On the night that Monica Kimani was brutally killed, Irungu says that he was with Maribe and has denied killing the lady in Kilimani.
Maribe is being held at the Gigiri Police Station ahead of her presentation in court.
