I have no idea what actually occurred here, but I like the idea of classes being cancelled due to demonic havoc. The Jamaica Star attempts to explain what unfolded:
Classes ended prematurely at a Corporate Area high school last Thursday following reports that there were demons at the institution, one of which possessed a female student.
The demon discouraged other students from praying for the possessed girl warning them that if they disobeyed he would leave the girl’s body and enter theirs instead. The school’s administration [sought] the assistance of a special prayer team that specialises in demon possession.
Subsequently, the school’s administration summoned students to a general prayer assembly feeling confident that the scare had ended, but they were in for a surprise. “In the middle of assembly, suddenly out of the ceiling, a bird’s head, cut off from the bird, dropped down. It was chaos after that,” a source who witnessed the incident said.
