On Friday, students from Bishop Noll Institute students in Hammond, Indiana, traveled to Andrean High School in nearby Merrillville for a basketball game.
"During the course of that game, a group of Andrean students produced signs and images of presidential candidate Donald Trump and began to chant 'Build that wall,' at the Bishop Noll team and fans, who are heavily Hispanic," the Catholic Dioceses of Gary, which oversees both schools, said in a statement.
Ashley Howard was at the game cheering for her cousin, who plays for Bishop Noll.
"When I looked across the gym, the signs that I saw from Andrean were the Trump fathead posters, the ESPN Deportes sign, a sign from 'Dora the Explorer,' and the 'Family Guy' Hispanic maid," Howard told CNN. She posted two photos from the game on her Facebook page. One showed a young man holding up a large Donald Trump face cutout. The second showed a group holding a banner reading "ESPN Deportes."
"Deportes" is Spanish for sports.
The signs, she said were coupled with chants like "Build a wall," "No comprende" and "Speak English."
"It was disturbing," said Howard. "I was shocked. After a while not seeing the administration come over and say that was enough, I was disgusted. I coach volleyball at another high school. I was more disappointed in the adults."
CNN calls to Andrean High School Principal Rick Piwowarski were not immediately returned, but Diocese of Gary spokeswoman Debbie Bosak told CNN that school administrators were quick to respond.
"There is a false perception that this was allowed to continue," Bosak told CNN. "As soon as administrators saw that this was happening, they shut it down. No one turned a blind eye to it. This was not something to be tolerated or condoned."
Administrators from Bishop Noll and Andrean met on Sunday to discuss the incident, she said.
"There will be repercussions for students, but due to privacy laws we can't discuss them. But there will be consequences," said Bosak.
'I was born in Dallas County, just like you'
On Monday, four days before the Indiana game, about 400 miles to the west, the basketball teams from Perry High School and Dallas Center-Grimes High School played in Adel, Iowa. Nearly half of Perry's student body is Hispanic.
