Aisha Abubakar, a housewife, has been arrested in Katsina State.
She was nabbed by the Nigerian police for murdering her four-year-old stepdaughter with rat poison in Katsina State.
The incident happened on Tuesday at Rimi in the Rimi Local Government Area of the state.
SaharaReporters learnt that Abubakar took the life of her stepdaughter and namesake, Aisha Abubakar to punish her mother for accepting to become her husband's second wife.
It was gathered that Abubakar had been nursing grudges since her husband left her and proposed to the mother of the deceased girl. However, it was learnt that she later reunited with her husband.
Narrating how she killed the little girl, Abubakar said, "Her mother travelled and left her in my care; that was how I took the advantage and added rat poison into her food.
"I'd been bitter for over four years because before my husband took the deceased person's mother as his second wife, he sent me packing before he later restored our marriage.
"I killed her to vent my anger and to punish her mother and my husband put together for traumatising me," she said.
The spokesperson for the Katsina State police command, SP Gambo Isa confirmed the incident, saying "she (Abubakar) killed her stepdaughter with rat poison and spared her own three children".
