From the Arcata Police Department:

On 5/7/18 at about 5:40 PM, the Arcata Police Department was notified of an e-mailed threat sent to the Arcata School District. 

The Arcata Police Department worked immediately with the school district and contacted the Federal Bureau of Investigation (FBI) regarding the threat. 

Through the investigation, it was determined that the e-mail was a hoax, originating from outside of the Humboldt County area.  Arcata School District appears to be the only local school district to receive the e-mail.  The Arcata School District includes Sunny Brae Middle School and Arcata Elementary School as well as the property occupied by Coastal Grove Charter School.

The Arcata Police Department takes all threats of violence against our schools very seriously.  Remember, if you see something, say something.
