Overview
- A large fight involving about 100 people broke out during the 559 Fights Next Gen 4 card, stopping the show on Saturday night.
- Visalia officers on site requested backup and 26 Visalia units plus deputies from the Tulare County Sheriff’s Office and officers from Farmersville and Exeter responded to regain control.
- Fifteen people were arrested and booked into the Tulare County Adult Pre‑Trial Detention Facility, and three Visalia police officers suffered minor injuries and were treated and released.
- Video from inside the convention center circulated showing groups converging as on‑site security tried to separate participants, and 559 Fights described the melee as isolated while pledging bans for anyone confirmed to have taken part.
- Authorities have not yet identified what triggered the initial confrontation or whether the arrested people were tied to specific teams, leaving open the possibility of more charges or policy changes for the promoter and venue.
