Nearly two dozen students from two high schools were involved in a brawl that stemmed from a basketball game the night before.
Fourteen Stonington High School students drove to Waterford High School on Thursday for a confrontation, according to police.
Students from both schools allegedly traded jabs over social media throughout the night and it culminated with the fight.
"Somebody got kicked in the face with really hard boots and his face is messed up," Waterford High School junior Katie Shea said.
Police said the animosity started the night before when Stonington visited Waterford for a regional basketball showdown. Eyewitnesses said some in the crowd got out of line.
"Somebody from Stonington threw a water bottle at somebody from Waterford," Waterford High School junior Lauren Shea said.
However, the fight escalated on social media.
"That's where everything gets planned and stuff," Lauren Shea said.
Police said apparently, the plan was to settle it at school. Around 4 p.m., after the day ended, police said carloads of Stonington students rolled up, ready to fight.
Police said it was a 14 on 8 brawl with Stonington outnumbering Waterford. No players took part, according to police.
Police said two kids were hurt, suffering from facial injuries. But police said they should be OK.
"We have never had this happened and are looking into why this did occur," Waterford Police Lt. Stephen Bellos said.
Police said they used an online footprint, surveillance photos and student cooperation to make arrests. They said potentially 20 summons will be issued on Friday.
"Some people got really injured and they deserve to get in trouble for that," Lauren Shea said.
The participants in the fight were not identified because they are juveniles.
Waterford and Stonington aren't rivals. But speaking with students, after this week, they might be.
Waterford pulled out a two point win in that hotly contested game earlier this week.
