A man suspected of sending a threatening email and post that prompted UCLA to cancel all in-person classes Tuesday was in custody in Colorado, the school said.
"I am greatly relieved to share that law enforcement officers in Colorado have taken into custody the individual who made threats against some members of our UCLA community yesterday," Administrative Vice Chancellor Michael Beck said in a statement Tuesday afternoon.
"While we will continue with our plans to keep instruction remote today, with this development, we will return to in-person instruction tomorrow," Beck said.
UCLA tweeted late Monday said the “UCLA Police Department is aware of a concerning email and posting sent to some members of the UCLA community today and actively engaged with out-of-state law enforcement and federal agencies.”
A subsequent tweet said: “UCPD is actively working with out-of-state & federal agencies on threats sent to some members of our community. Out of an abundance of caution, all classes will be held remotely Feb 1. We will keep you updated.”
Los Angeles police told NBC Los Angeles on Tuesday that they previously had contact with the man suspected of posting the threats.
Police Chief Michel Moore said the department's Mental Evaluation Unit had contacted the man last spring. The nature of the contact was not immediately released.
The FBI confirmed to NBC News on Tuesday that it was working with UCLA authorities “to assess the situation.”
UCLA’s executive communications officer, Steve Ritea, said out-of-state law enforcement officers had confirmed that “the person who made the threats to UCLA is under observation” and not in California. “Classes will remain remote today,” he added.
The Los Angeles Times reported that an email was sent to students and faculty informing them that a former university lecturer and postdoctoral fellow had sent a video talking about a mass shooting and an 800-page “manifesto” with “specific threats” toward the department.
The Times obtained part of the email, which included links to the manifesto and the video. NBC News has not seen or independently verified the contents of the emails.
The Times and The Daily Bruin, the campus newspaper, identified the lecturer; NBC News has not independently confirmed the identification. The person did not immediately respond to a message seeking comment Tuesday.
