A police officer attached to Litein AP camp Kericho killed herself after her lover allegedly jilted her.
The younger officer rushed to the armory, picked her AK 47 rifle and shot herself dying on the spot.
According to close friends of the deceased, the Saturday incident was caused by an argument between the two after the man said they end their relationship.
The lover is a Kenya Wildlife Service warden, a source said.
Her body has since been moved to Kapkatet district hospital mortuary.
A senior police boss said officers should seek counsel when overwhelmed by troubles instead of taking drastic actions.
