The Inter-College Rugby Union, traditionally a showcase of Tongan sportsmanship and youth leadership, descended into chaos Friday as violent clashes between school factions erupted.

Viral videos allegedly showed alumni both celebrating and instigating the brawls.

It follows Tonga Police issuing “all students, ex-students, and supporters to uphold peace and show respect during Friday’s Inter-College Rugby Union event.

“This is a time to celebrate school spirit, talent, and sportsmanship. Let’s ensure that our support builds pride,” the statement read.

Authorities announced their presence throughout the tournament, with mounted patrols monitoring crowd behaviour and additional officers stationed at potential hotspots.

The police statement outlined clear expectations: positively supporting schools, respecting officials and opponents, avoiding violence or disorderly conduct, and complying with all security instructions.

According to footage shared on social media and seen by Kaniva News, multiple fights erupted in downtown Nuku’alofa and surrounding areas.

Witnesses described chaotic scenes of physical altercations and thrown objects at Hihifo before onlookers stepped in and restored order.

It is unclear whether any arrests were made.

Police emphasised their zero-tolerance approach, warning that instigators of further disturbances would face immediate consequences.

“We remind everyone that Police operations are in place throughout the event and surrounding areas to ensure safety and public order.

“Any form of violence or disruption will be dealt with appropriately.

“Let’s make this a safe, enjoyable, and memorable occasion for our youth and our nation.”
