Nigerian police are investigating a bizarre claim that a boy has been turned into a yam by a witchdoctor, the Daily Star claims.
Officers have even taken a large yam into custody.
Three schoolboys in Maiduguri told their headteacher their friend had been transformed into a vegetable in front of their eyes after accepting a sweet from a stranger.
As word spread about the schoolboy yam, hundreds of curious people began flocking to the police station to catch a glimpse of it.
