Parraz said racial tensions boiled over at the school this year around the Cinco de Mayo holiday.

Alicea's parents said he flies the flag from his bike as a tribute to veterans in his family.
"He's got that flag on his bike because he's proud of where he comes from," Alicea's father, Robert Kisner, said.
Alicea folds up the flag and keeps it in his backpack while attend class, the TV station said.
