A high school senior in Miami has been arrested and is begin charged with allegedly hacking into the schools report card system changing his, along with at least 4 other students grades.

18 year old student, Jose Bautista, was arrested on Thursday after the school principal turned him into the police. Bautista is facing charges of intellectual property offense, modifying programs and an offense against computer users, CBS reported.

Jose Bautista appeared in front of a judge Friday and had his bond set to $20,000 along with house arrest with a GPS monitor.

The high school student allegedly approached fellow students and asked if they wanted their grades changed. Friends whose grades were reportedly altered said Bautista approached them at the beginning of the year with the proposal up until February.

Bausista allegedly gained unauthorized access to the school’s grading system, changing students grades as well as other information at Dr. Michael M. Krop Senior High School, according to the arrest report.

The principal at Dr. Michael M. Krop Senior High School, the school Bautista attended, said Bautista gave him a written confession.

A senior student at the school told CBS news “That was taking it to an extreme, I was surprised, it’s the end of the year and grades are going in, for a kid to do something like that I guess he felt he had to.”

It is still unclear whether Bautista will be allowed to graduate with his class. As the case is still under investigation it is unclear if students who had their grades changed by the senior will face any punishments.

After the attack, Miami-Dade schools released a statement reading “The school district takes incidents like this very seriously. In addition to the arrest and ongoing criminal investigation, the Code of Student Conduct provides for corrective strategies up to and including recommendation for expulsion.”
