MURFREESBORO, Tenn. (AP) - Middle Tennessee State University officials canceled classes Thursday and Friday, saying they had received a credible threat.
University President Sidney McPhee sent an e-mail to all faculty, staff and students at midday Thursday, saying "a credible threat to our campus has been made." He did not elaborate.
MTSU spokeswoman Lisa Rollins said three threatening e-mails had been received since Wednesday evening. Authorities were tracing them Thursday, she said.
She described campus Thursday afternoon as "pretty quiet. No one is walking around." Students had been taking midterm exams until classes were canceled.
Rollins said the e-mails did not say how people would be harmed. She said concern was heightened by the setting of three small fires on campus a week ago.
