ORONO (AP) – Count Maine among the states where campus threats have created disruptions following the shootings at Virginia Tech.

A bomb threat was called into the University of Maine police department Wednesday morning. The university community was alerted via e-mail and handbills, but the threat does not appear to be credible, said spokesman Joe Carr.

The campus remained open but professors were given the choice whether to hold classes. Bomb-sniffing dogs checked out Memorial Union to give students a place to go if they didn’t feel safe elsewhere on campus, he said.

The threat came one day after university President Robert Kennedy ordered a review of the campus firearms policy in light of the Virginia Tech massacre.

Students are currently permitted to have weapons on campus, but they must be registered and stored with the university’s Department of Public Safety.

“I believe we have good compliance,” said Noel March, public safety director.

Most weapons stored at the Public Safety Building are hunting rifles, paintball guns for the schools paintball club, and the occasional martial arts gear, sword, or bow and arrow.

“The students take it very seriously that we have a rule that says no weapons are allowed on campus,” March said. “Our practice of providing a facility for the secure storage of these items makes good sense. It’s good risk management practice.”

Any policy changes would not take effect this semester, but Kennedy said the rules would be examined in the context of what other universities do.

“It could be that we don’t change anything,” he said.

Campus threats forced lock-downs and evacuations at universities, high schools and middle schools in at least 10 states on Tuesday.

Threats in Louisiana, Montana and Washington state directly mentioned the massacre in Virginia, while others were reports of suspicious activity in Texas, Arizona, Oklahoma, Tennessee, North Dakota, South Dakota and Michigan.

The bomb threat at the University of Maine was nonspecific and did not mention the Virginia Tech incident, Carr said.
