The Delhi Police on Thursday arrested a woman and her partner for allegedly killing her six-year-old daughter in Ghazipur after the child found out about their love affair, PTI reported. The child had reportedly threatened to inform her father about the woman’s affair.

The police found the child’s body on a neighbour’s terrace after they responded to a call reporting that the child was missing. The woman and her lover strangled the child before slitting her throat on Wednesday, the police said. The woman then roamed around the neighbourhood and claimed that her daughter was missing.

Neighbours told police officials about the woman’s alleged affair, Deputy Commissioner of Police (East) Omvir Singh told the Hindustan Times. “The couple planned to kill the girl after she threatened to inform her father,” Singh said. The woman lived with her husband, a cart-puller, and three children. Her partner lived in the same neighbourhood.

The police said the woman’s phone records confirmed that she had conspired with the other accused to kill her daughter. “Both have confessed to their crime during interrogation,” Singh added.
