SAN DIMAS (CBSLA.com) — Two students were in custody on Friday after allegedly hacking into their high school’s computer system to change grades in exchange for cash.

On Thursday — which was the last day of school — detectives responded around 11:30 a.m. to San Dimas High School, located in the 800 block of West Covina Boulevard, for report of a cyber crime within the Bonita Unified School District.

A preliminary investigation revealed two adult students gained unauthorized access to secure information on the school’s computer network.

Teachers said they noticed grade changes and discrepancies while entering grades into the system.

With the help of the district’s computer information services, authorities were able to trace back to find where the students gained access from.

Authorities said the students hacked into the network using the school’s website, deputies explained.

In response, school district officials took the homepage website down as it was found to be the access point.

The two adult students were subsequently arrested for unauthorized computer access and fraud. Authorities have not released the identities of either student at this time.

The investigation is ongoing.

Anyone with information regarding this incident is urged to contact the Los Angeles County Sheriff’s Department’s Fraud and Cyber Crimes Bureau at (562) 347-2602.
