MANILA, Philippines—(UPDATE) Five more students suffered from seizure as “evil spirits” continued to “haunt” a public high school in Calapan City, Oriental Mindoro province, Friday, a school official said.

The five new cases brought to 26 the number of students “possessed” in a month at the Pedro Panaligan Memorial National High School.

Classes resumed Friday morning after weeks of disrupted sessions, but the new seizure incidents prompted administrators to indefinitely suspend classes again, school principal Henry Tungol told INQUIRER.net.

On Friday afternoon, paranormal healers again tried to drive away what residents believe to be evil spirits, teacher Anna Liza Teves said.

But she said only three victims attended Friday’s healing session as the other “possessed” students have their own faith healers.

In past years, there were one or two cases of "evil possession" reported but in the last week of July as many as 25 students had "seizures," Tungol earlier told the Philippine Daily Inquirer (parent company of INQUIRER.net).

Four of the five who experienced seizures Friday had been previously “attacked” by the evil spirits, Teves said.

The victims were crying in pain as they suffered from seizures and shortness of breath, she said.

The school, located in the village of Comunal, has not been holding regular classes since August 8 because of various instances of "evil possession," he said.

The victims, mostly girls, have pointed to evil spirits apparently incensed by the cutting of a decades-old tree in the school’s backyard.

A mass was said by a Catholic priest at the request of terrified students and parents.

On Friday last week, local healers offered two black pigs in a bid to appease the angered spirits.

Still, the haunting continued.
