Citizen TV anchor Jaque Maribe was on Saturday night arrested by DCI detectives in relation to the ongoing investigations into the murder of business lady Monica Kimani.
Directorate of Criminal Investigation George Kinoti confirmed the arrest saying the TV star was taken to Gigiri police station.
Maribe was on Thursday questioned by the DCI at Kilimani police station and the DCI headquarters on Kiambu Road.
She returned at the headquarters on Friday where it is believed she recorded a statement.
Maribe became a person of interest after her car was allegedly used on the night of Monica's murder.
The vehicle was on Thursday dusted by forensic experts.
Her fiancé Joe Irungu, who has been in custody since his arrest on Tuesday, is being held as the key suspect in the murder.
Investigations revealed that he was the one driving Maribe’s Toyota Allion on the night of Monica’s murder.
Irungu has since denied involvement in the gruesome murder.
He told the police he was shot on his chest by thugs he believes may have committed the heinous crime.
Kinoti, however, said investigations indicated that Irungu's gunshot wound was self-inflicted, pointing to a possible suicide attempt.
On Saturday, the detectives working on the case said they had made major progress in their investigations after conducting a search at Maribe's apartment in Lang'ata.
The detectives also arrested Brian Kasaine, a man believed to be the owner of a gun found in Irungu's possession.
Monica’s lifeless body was found by her sister who came visiting in a bathtub in her Kilimani apartment with her throat slit.
She was buried on Friday at her parents' rural home in Gilgil at an emotional send-off.
