Pasadena police Lt. Tracey Ibarra says the two men and a woman - all siblings in their 20s - were arrested Monday evening after people reviewed video and interviewed people who saw the fighting among tailgating fans.
Ibarra says all three are children of a 44-year-old man who was arrested for investigation of attempted murder after two men were stabbed in the melee. One victim remains hospitalized.
Two other men were charged Monday with resisting arrest and other crimes related to the brawl.
The new arrests were first reported Tuesday by the Pasadena Star-News.
