This came over USC's emergency bulletin service a little before 8:30 PST - we got it once by email and then again over SMS. It's ninety-nine percent certain to be a false alarm - commencement is tomorrow, they swept the campus, and they found something square in a corner. On the other hand, commencement is tomorrow:

Suspicious object found in EVK, New North. Area has been evacuated. Please stay away until further notice.

We'll update when they sent out the "this was a shoe box filled with a three week old sandwich that some undergrad left behind" all clear.

UPDATE: Curiouser and curiouser. An email from TransNet, a totally separate part of the University bureaucracy responsible for all aspects of campus transportation:

Due to heavy traffic around campus this evening, all tram routes that travel through campus will be immediately suspended. This includes Route A,B,C and the Parking Center. Service planned for tomorrow's commencement will resume at 6 AM.

Students are moving out so it's not impossible that this bulletin is unrelated to the EVK evacuation. Although it's weird that they would spam everybody with this at 8:36pm - long after most of the trams have stopped. Still nothing on the local news so we're inclined to shrug it off.

UPDATE: Yeah:

At 9:10pm suspicious object found at EVK/New North was deemed safe. Area will be opened shortly.
