LOS ANGELES (AP) – A man who allegedly threatened the University of California, Los Angeles, and detailed potential violence against the prominent university over hundreds of pages has been taken into custody in Colorado following a standoff Tuesday.

The man – identified as Matthew Christopher Harris, 31 – was taken into custody Tuesday morning and is being held in Colorado on state charges after a standoff with police in Boulder. Federal charges may be pursued.

It wasn’t immediately known if Harris had a lawyer who could speak on his behalf. Authorities were searching his Boulder apartment.

“Upon reviewing parts of the manifesto, we identified thousands of references to violence, stating things such as killing, death, murder, shootings, bombs, schoolyard massacre in Boulder and phrases like ‘burn and attack Boulder outside of the university,'” Boulder Police Chief Maris Herold said at a news conference Tuesday.

The investigation in both states began Monday after Harris allegedly sent a “threatening email” to members of the UCLA community with a link to his 800-page manifesto threatening violence, officials said. UCLA police tracked Harris, a former postdoctoral philosophy fellow at the prestigious university, to Boulder and reached out to law enforcement there.
