A public high school in Oriental Mindoro in central Philippines had been suspended since August 8 after an "evil spirit" haunts the school ground and "possessed" students since.
Henry Tungol, principal of the Pedro Panaligan Memorial National High School said students have shown signs of "seizures, shortness of breath while some were shouting and writhing in pain. The events have caused hysteria inside the campus.
Tungol said even students who have already gone home have shown signs of being possessed.
A girl was said to be observed by her parents to be staring blankly at nothing before having a seizure attack.
Last July, at least 25 students suffered seizures and classes had to be suspended. Students point to evil spirits that were angered by the cutting of a 40-year-old tree some four years ago.
Classes have been disrupted from August 8 until August 19 because of various stages of "evil possession."
School officials have offered two black pigs to appease the angered spirits and invited local healers or quack doctors to drive away the evil spirits.
