LOUISVILLE, Ky. (WDRB) -- More than two dozen Indiana high school seniors are not allowed to walk at graduation after a senior prank went too far. 

The prank happened Tuesday night at the Crispus Attucks High School in Indianapolis. 

The teens planned to write on walls with chalk and decorate the school with balloons, but school leaders say some of the teens broke off from the group and caused major damage by spraying a fire extinguisher and pulling the fire alarm, causing the sprinklers to go off.

Some students and parents say the punishment is too harsh.

"'I'm the first to graduate out of my family and it's not fair," said Elizabeth Huerta, a graduating senior.

School officials say the students are also required to join a beautification project at the school.
