SYRACUSE, N.Y. (AP) — Police at Syracuse University are investigating reports that a white supremacist manifesto was posted online and shared at a campus library.

The reports Tuesday that a manifesto was posted online and “air dropped” to several cell phones comes as the upstate New York college is investigating a series of recent racist episodes.

Police from the university, the city and state and the FBI are investigating the origin of the document. Police say there appears to be no direct threat.

Chancellor Kent Syverud on Sunday suspended one fraternity along with social events for the others after a black student complained she was verbally harassed.

Gov. Andrew Cuomo on Tuesday criticized Syverud’s handling of the incidents and called on the college to immediately bring in a monitor to investigate.
