Millbrae Man Arrested Following Intensive Investigation into Criminal Threats

A Millbrae resident has been taken into custody on suspicion of making serious criminal threats, sparking concern and a swift response from local law enforcement. Authorities confirmed the arrest of 45-year-old Johnathan Miller on Thursday, August 29, 2025, following an extensive investigation into allegations that sent ripples through the community.

The incident began earlier in the week when the San Mateo County Sheriff's Office, which provides police services to Millbrae, received credible reports regarding a series of disturbing threats.

These threats, whose specific nature has not been fully disclosed due to the ongoing investigation, were deemed serious enough to warrant immediate attention and a dedicated effort to identify and apprehend the individual responsible.

Investigators worked diligently, piecing together evidence and following leads that ultimately pointed to Miller.

The arrest took place without incident at his Millbrae residence, where officers served a warrant. Miller was subsequently booked into the San Mateo County Jail on suspicion of making criminal threats, a felony offense under California Penal Code section 422.

Law enforcement officials emphasized their commitment to ensuring public safety and taking all threats seriously.

They highlighted the importance of community vigilance and reporting suspicious activities. The San Mateo County District Attorney's Office is currently reviewing the case, and formal charges are expected to be filed soon.

Miller is currently being held on $50,000 bail. The Sheriff's Office has indicated that the investigation is active and ongoing, and they are urging anyone with further information relevant to the case to come forward.

Residents are reminded that all individuals are presumed innocent until proven guilty in a court of law.
