Parents in Peru are concerned that 'demonic forces' have possessed their children following an incident at a boarding school involving a ouija board—although others are blaming the incident on mass hysteria.

The children were reported to have been found incoherent and writhing on the floor by a teacher who arrived in their classroom after hearing strange noises.

Witnesses said that a teacher's daughter brought a book of 'black magic' and a ouija board to the school in the native community of San José de Saramuro, located in the province of Loreto.

The girl is accused of encouraging her classmates to play with the ouija board, and of painting diabolical symbols on the door of the school bathroom.

Many of the concerned parents have taken their children to various evangelical churches to be ministered to by a pastor.
