Authorities on Wednesday arrested an engineering student from the University of Central Florida accused of hacking computer system and changing his grade from F to B which under the state of Florida is a crime.

The culprit, 22-year-old Mr. Sami Adel Ammar was reported by his professor to the authorities who alleged him of tampering with his grades. According to the professor, Ammar “had only completed one assignment the entire semester” which makes it obvious that he would have ended up with low grades, not B.

Upon investigation, police found an IP address of the computer system which was hacked by Ammar to change his grades. A surveillance video also helped the police to identify Ammar and another person at the same location where the hacked computer was at the time when grades were changed.

It’s unclear who the second person was; Ammar, on the other hand, has been arrested and currently in the Orange County Jail. However, this is not the first time when a student has been caught tempering their grades. Previously, a Kennesaw State University student was arrested for hacking into his school’s computers and modified his own as well as his four classmates’ grades.

In another incident, two students from San Dimas High School, California were arrested on suspicion of hacking their school’s computer system and tempering the grades of around ten students. While in 2015, a 14-year-old student from Florida’s Paul R. Smith Middle School was arrested for bypassing the school’s computer security network and gaining access to the server that contained data related to FCAT (Florida Comprehensive Assessment Test).
