NEWPORT BEACH, California — Authorities have filed additional charges against the tutor at the center of an alleged high school grade-changing scandal in Orange County.
The county district attorney's office said Friday that 29-year-old Timothy Lai faces an additional 16 charges of computer access and fraud.
Prosecutors say Lai pleaded not guilty to the new charges. A message was left for Lai's lawyer.
Lai pleaded guilty last year to four counts of computer access and fraud and one count of second degree commercial burglary.
Prosecutors say Lai was working as a private tutor when he broke into a building at Corona Del Mar High School in Newport Beach and planted keylogging devices on computers.
Authorities say that information was used to break into the school's computer system, steal exams and change students' grades.
