LOS ANGELES (AP) — UPDATE: UCLA officials say a man who threatened members of the university was taken into custody in Colorado on Tuesday.
University of California, Los Angeles, officials have ordered all classes to be held remotely due to threats.
UCLA took the step Tuesday, a day after students returned to in-person instruction and university officials say the move was made out of an abundance of caution.
The Los Angeles Times reports that it obtained emails sent to students and faculty showing that authorities are investigating a former UCLA lecturer who allegedly sent a video referencing a mass shooting and an 800-page manifesto with threats against the philosophy department.
UCLA did not confirm the Times' report but says university police are aware of a "concerning" email and posting sent to some members of the UCLA community.
