That outbreak of ugly violence before last weekend's big USC-UCLA game was a family affair, at least partly, authorities allege.

While the father of the Cisneros clan was arrested and released in connection with the brawl at the Rose Bowl, three of his children continued to face serious charges following the football hooliganism.

Anthony Richard Cisneros, 22 (two counts of attempted murder), Arthur Joseph Cisneros, 25, and Akira Sheree Cisneros, 24, (one count each of assault likely to produce great bodily injury) pleaded not guilty in Pasadena Superior Court Thursday.

Police believe Cisneros was at least one of the knife wielders that helped to send to men to hospitals with serious injuries about three hours before last Saturday's game.

Forty-four-year-old Arturo Cisneros of Northridge had been arrested, then released. But Pasadena police told the Weekly earlier this week that he's not out of the woods yet: Their investigation continues.

Amateur video, police told us, helped them track down the sibling suspects.

The brawl broke out when a football from a touch football game hit a parked Mercedes and fans on either side of the college rivalry had it out.

Two others, 24-year-old Joshua Elder of Temple City, and 27-year-old Steven Radu of Monrovia, pleaded not guilty to lesser charges in connection with the brawl.
