A hard plastic case that exploded on the campus of Northeastern University in Boston causing minor injuries to a staff member contained a rambling note that railed against virtual reality and also referenced Facebook founder Mark Zuckerberg, a law enforcement official said Wednesday.

Investigators are still trying to identify the motive behind the Tuesday evening explosion and are working to understand why the package was specifically sent to Northeastern, the official said.
