Police in Nakuru have arrested a boy who they suspect defiled and murdered a Grade Six pupil in Lare, Njoro.

Sub-County Police Commander Stanley Koech said the 16-year-old fled after the murder of Mercy Nyambura on Monday evening.

"After getting a tip on who the suspect could be, our investigative team immediately began a manhunt. He escaped from his parent's home within the village,” said Koech.

The minor was arrested at his aunt's home in the neighbouring Mau Narok Ward.

Police claim the boy confessed, saying he was possessed. “We are making a miscellaneous application today to hold him for some days as we conclude our investigations. He claimed that some spirit led him to attack the girl,” said Koech.
