A tipper left notice yesterday that another Massachusetts college campus found "threatening notes" in the school bathrooms. After notes appeared at Bridgewater State and Framingham State, a janitor found notes in UMass-Amherst bathrooms.

In the note found at Framingham State, threats included references to leap year, which falls on Friday.

No one has said if there's a link among all the notes in the school bathrooms, but officials aren't playing around after what happened at Northern Illinois University. Anyone who works or studies on a campus shouldn't be surprised to see a rise in police presence over the next few days.
