Students hack into Bloomfield Hills school information system, manipulate grades

The mother of a student at Warren Mott High School says a dispute during school hours later led to a vicious beating at a Target store at 12 Mile and Dequindre. Students hacked into the Bloomfield Hills student information system, according to a Facebook post. The student information system houses all the student and family data. School officials said the students manipulated personal grades, attendance and lunch balance information for a small number of Bloomfield Hills High School students.
