Administrators at a California high school sent five students home on Wednesday after they refused to remove their American flag T-shirts and bandannas -- garments the school officials deemed "incendiary" on Cinco de Mayo.

The five teens were sitting at a table outside Live Oak High School in Morgan Hill, Calif., on Wednesday morning when Assistant Principal Miguel Rodriguez asked two of them to remove their American flag bandannas, one of their parents told FoxNews.com. The boys complied, but were asked to accompany Rodriguez to the principal's office.

The five students -- Daniel Galli, Austin Carvalho, Matt Dariano, Dominic Maciel and Clayton Howard -- were then told they must turn their T-shirts inside-out or be sent home, though it would not be considered a suspension. Rodriguez told the students he did not want any fights to break out between Mexican-American students celebrating their heritage and those wearing American flags.
