Shasta High School is currently on lock down because of a threat of violence. 

The principal of Shasta High School, Milan Woollard, said that they received a threatening phone call from a "unidentified individual that made mention of possible explosive devices on campus and/or an armed subject enroute to the school." Then they called in Redding Police to check out whether it was a viable threat.

Woollard said that the police said the threat was not credible and Redding Police released a statement saying that no suspicious devices or potential suspects were found on the campus.

A police officer on the scene confirmed that the school was under a lock down because of a general threat. 

Students at the school were released at the normal time.
