Two people were arrested after fights broke out at Rio Vista Park, where high school students from across the region gathered as part of a "senior skip day". The police responded to a social media post and large crowds gathered, with an estimated 2,000 people. The police closed the park at around 3:30pm, assisted by outside agencies due to safety concerns. The arrests resulted in two charges of 17-year-old women and a 17-yr-old man for assault on a Peace Officer.
