RAPID CITY, S.D. (AP) — Officials at the South Dakota School of Mines and Technology say an email that a university employee inadvertently sent to graduate students included an attachment with names, student identification numbers and grade point averages of about 350 students.

Spokeswoman Dani Mason says Social Security numbers were not included in the attachment.

All students who received the email have been told to delete it and to confirm that they've complied.

Mason says the Rapid City school is determining additional steps to ensure a similar incident doesn't occur again.
