In what is suspected to be a macabre tantric ritual, the body of a three-year-old girl was found with her throat slit in a village in the district, the police said Monday.

A woman allegedly practising witchcraft has been arrested, police said. Chinnappillai took the girl, who was playing in front of her house at Kurumpatti, into the forest and allegedly killed her believing that a child sacrifice would increase her tantric power, they said.
