AUSTIN, Texas (AP) — Authorities evacuated buildings Tuesday at St. Edward's University after a threatening note was found, a school official said.

The bomb threat came a day after a Virginia Tech student killed at least 30 people locked inside a classroom building in the deadliest shooting rampage in modern U.S. history.

Police officers had secured the perimeter of the campus and were searching the buildings, university spokeswoman Mischelle Amador.

She declined to say where the note was found and said its contents were "nonspecific."

Students who live on campus were being allowed to return to their dormitories as police finished searching each building, Amador said. Faculty, staff and all other students were asked to stay away from the campus, and morning and afternoon classes were canceled.

About 5,200 undergraduate and graduate students are enrolled at the Catholic university south of downtown Austin.

Amador said the university's reaction was not influenced by Monday's attack at Virginia Tech.

"No matter what day or when this would have happened, we will always take the necessary precautions to protect our students, our faculty, our staff, the entire university community," she said.
