Police negotiate for nearly 3 hours with 40-year-old who threatened to kill a man; also arrested last month

By Lt. Michael Mellone, Antioch Police Department

ANTIOCH, CA – Antioch police took an armed barricaded suspect into custody Wednesday afternoon, April 8, 2026, following a nearly three-hour standoff at a home on Catanzaro Way.

At about 1:40 p.m., dispatchers received a 911 call reporting a man had pulled a knife and threatened to kill a man at a residence in the 5200 block of Catanzaro Way.

Responding officers identified the suspect as Derek Bradshaw, 40, of Antioch, who was armed with multiple throwing knives and had barricaded himself inside the home.

Crisis Negotiation Officers, along with the Angelo Quinto Community Response Team and Contra Costa County A3 Crisis Response, responded to the scene. Negotiators worked for several hours to convince Bradshaw to surrender peacefully.

During the standoff, Bradshaw climbed onto the roof of the residence and continued to refuse officers’ commands. Officers formed a tactical plan and were able to safely take him into custody.

Bradshaw was arrested on charges of felony criminal threats (Penal Code 422) and brandishing a deadly weapon (Penal Code 417(a)(1)). He will be booked into the Martinez Detention Facility

after receiving medical clearance at a local hospital.

No officers, bystanders or community members were injured during this incident.

The Antioch Police Department would like to thank personnel from the Contra Costa County Fire Protection District and American Medical Response for their assistance at the scene. We would also like to express our appreciation to area residents for their patience and assistance while officers worked to bring this incident to a safe resolution.

According to localcrimenews.com, Bradshaw is White and was arrested last month also by Antioch Police for battery on a person.
