Were Kids Possessed by the Devil at Knysna School?

Were 2 students possessed by the devil at Concordia High School in Knysna? Was the school's teen stabbing the work of the devil too... or Amakhubalo spirits who've been blamed for other disturbances across South Africa?

It's a topic that's had residents of the northern communities abuzz. In central town, yesterday, a waitress insisted that the two students couldn't move from their chairs and were speaking in strange tongues. Although that was second-hand info, she was adamant. I mentioned that there are christians who spoke in tongues too but my tongue fell on deaf ears.

What is fact, as reported by the Knysna-Plett Herald, is that, Prophet Siyanda Njoloza of the Kingdom Life Apostolic Ministries was called to the school by staff. And the staff were barred from speaking to the media.

Did the school make the right decision?

Are these instances of crime, attention seeking, drugs, mass hysteria, the psychologically disturbed... or possession at the hand of satan?
