After reports of an armed person on the Ventura College campus Tuesday evening, law enforcement officials were unable to locate any suspects or victims, though the campus was put under a shelter-in-place order while officers investigated.

The Ventura County Community College District Police Department announced on Twitter that it and the Ventura Police Department were investigating, but “there is currently no confirmation of the threat.”

VPD said the search began after an automatic alert was received by the college’s staff.

“The original source of this message is currently unknown, however we are in the process of searching and evacuating,” the VPD added on Twitter at about 7 p.m.

“As of now:

No known suspects
No confirmed shots fired
No victims
No witnesses”

At about 7:45 p.m., police confirmed that the reports were unfounded, and the school will be investigating how the misinformation was shared.

“The shelter-in-place order at Ventura College has been lifted,” district police said on Twitter. “Officers searched the campus and found no active threat. The false report was caused by an automated computer alerting system. College staff, IT, & police are currently investigating how the alert was sent out.”

“For the safety of our campus, classes have been cancelled this evening and the main campus is closed for the remainder of the day,” school officials added.
