Campus police at the College of William & Mary say someone on the campus received a threatening email that's similar to threats emailed to people at Virginia Tech.

Dozens of people at Virginia Tech got the threatening email Monday. Police said the message "included a threat to campus safety" but they did not elaborate. Classes continued as scheduled on Monday.

An alert from the head of the emergency management team at William & Mary says a similar email was sent to someone at William & Mary who has an affiliation with Virginia Tech. The threat was sent to that person's Virginia Tech email address.

The source of the emails is under investigation.

In 2007, a gunman killed 32 people on Virginia Tech's Blacksburg campus.
