A high school student was taken into custody for allegedly altering computer data, including students’ grades, police said.

The 17-year-old was arrested Monday at Corona del Mar High School and released to his parents after several hours of questioning, said Sgt. Steve Shulman. Police also searched the student’s home, removing computers and paperwork, Shulman said.

The move comes more than a week after school officials notified police of suspicious changes to grades of six juniors and one senior. The investigation continues and Shulman said others could be involved.

Juvenile court officials and prosecutors have not yet decided whether to pursue charges against the teen, whose identity has not been released. The student has been suspended for five days, school officials said.
