ST. CLOUD, Minn. (AP) - The U.S. Department of Education has closed an investigation into changes made to students' transcripts at St. Cloud State University.

The Office of Inspector General determined that "there appears to be no federal violation" of student loan rules and the "case is recommended for closure." That's according to information through a Freedom of Information Act request.

The department was investigating whether St. Cloud State failed to return federal financial aid money it was required to return if the students whose grades were changed became ineligible to keep that financial aid.

Federal officials were on campus in the summer of 2013, asking questions of current and former employees.

Professors had complained that grades they gave students were later removed from transcripts without their knowledge.
