From Clayton PD:
On September 17, 2018, Clayton Police were made aware of a threat of violence towards Diablo View Middle School via a hacked social media account. An investigation was conducted and a student was arrested this morning.
Earlier today a search warrant was conducted with the assistance of the Contra Costa County District Attorney’s Office at the juvenile’s residence. The juvenile was booked at juvenile hall on PC 422 (Criminal Threats) and PC 530.5 (Identity Theft).
We do not believe there are any additional suspects. The investigation is continuing and there are no other apparent threats to the school at this time.
