The bodies of six children in Tanzania have been found with their ears and teeth removed, authorities told the BBC.
Some of the bodies were also missing limbs and were badly mutilated.
The killings raised concern about witchcraft in the area, the Njombe region in south-western Tanzania.
Njombe District Commissioner Ruth Msafiri told the BBC that three of the children came from one family.
She confirmed that the children were taken away from their homes at night while their parents were away.
Two people have been arrested according to reports from the area.
The district commissioner has urged parents there to be alert.
