MANILA - The Ateneo de Manila University (ADMU) on Thursday said it is not taking lightly the bullying incident in its Junior High School campus that was captured on video.

The video, which shows a student challenging his schoolmate to a fight in a comfort room, has gone viral on social media.

In a statement, ADMU President Jose Ramon Villarin said an investigation is ongoing and the school administration is treating the incident "with the highest priority and urgency."

"Let me be very clear: the school does not condone such behavior. We have our codified standards of conduct and all students are made aware of these and their rights and responsibilities," he said.

"The school is not silent on its stand on violence and it will not hesitate to impose the penalty of dismissal or even expulsion in cases of grave misconduct."

The ADMU Junior High School earlier said it "is dealing with this matter seriously beginning with an immediate investigation that ensued the moment the report reached us."
