By the evening, the crowd had swelled to around 500 people and the protest had moved to the downtown Santa Ana area. Officers with the Santa Ana Police Department formed a skirmish line. Tran watched from Sasscer Park, around 30 feet away from the main crowd, as tensions rose. Police suddenly cleared the crowd with "barrages of rubber bullets, pepper balls, flash bangs, tear gas," Tran said, without warning or apparent provocation.
