Investigators say the student judicial system office, which houses the Honor Court, was targeted and "sensitive" confidential records for 31 students were taken.
The school did not identify the students in a news release. It said they were being notified.
The break-in was discovered at 8 a.m. Monday.
Anyone with information on the theft is asked to contact UNC Police Investigator Ross Barbee at (919) 962-0564 or CrimeStoppers at (919) 942-7515. All callers may remain anonymous.
