A 24-year-old was arrested over the suspicion that she stabbed her husband to death on Sunday night in Marurui, Roysambu in a family dispute gone awry.
Kasarani OCPD Muthuri Mwongera confirmed the incident saying the 27-year-old man only identified as Jimmy had been working as a casual labourer.
He had separated from his wife earlier in the year over a marital dispute before they made up and began living together again.
Jimmy reportedly moved in with his wife but had threatened to move out over the weekend after a dispute.
The suspect told police officers that her husband fell on a sharp object that tore through his collar bone.
Investigations into the matter have begun; the suspect is being held at the Kasarani police pending her appearance in court.
