Explosive thrown at Antioch house where arrest was made in July
Walnut Creek PD Bomb Squad assists again
Police seek unknown suspect, warn residents against vigilante justice following social media posts of videos showing “resident yelling and using racial slurs”
By Antioch Police Department
On Monday, August 17, 2026, at 10:11 a.m., Antioch Police Department officers responded to a residence in the Lake Alhambra area of Antioch after an incendiary device was reportedly thrown at the property. The device, preliminarily believed to be a large firework, exploded and caused minor property damage. No injuries were reported.
Officers secured the scene and collected evidence. The Walnut Creek Police Department Bomb Squad responded to assist with the investigation. APD officers have interviewed several witnesses, are collecting and reviewing surveillance video from the surrounding area and are pursuing several investigative leads. At this time, no suspect has been identified.
The residence is associated with several incidents from July 2026. One of those incidents, which recently received significant attention on social media, was addressed through the courts and resulted in a restraining order. In a separate incident involving a different victim, the same suspect was arrested for an alleged civil rights violation and battery. That case was referred to the Contra Costa County District Attorney’s Office, which subsequently filed misdemeanor charges alleging violation of civil rights and simple battery. The criminal case remains pending.
A post on the Antioch Police Department’s Facebook page Sunday afternoon, Aug. 16, also asked people not to pursue vigilante justice. It read, “We are aware of videos circulating on social media involving a local resident yelling and using racial slurs. The Antioch Police Department is actively investigating the incident.
“We understand that these videos may be upsetting to our community. We ask everyone to please allow our investigators to do their job and not take matters into your own hands or harass, threaten, or confront anyone involved.
“If you have information that may assist our investigation, please contact the Antioch Police Department.
“Thank you for helping us keep our community safe and respectful.”
According to the Antioch PD CitizenRIMS map, the incident, Number: 2608170070, is classified as felony vandalism of $400 or more and occurred in the 90 block of E. Lake Drive.
According to Lt. Bill Whitaker, an arrest was made at the house on July 27th of the man who was the subject of the videos in which he can be seen making racist comments. According to the APD CitizenRIMS map, the arrest occurred at 6:12 PM and was for a felony assault described as, “Threaten Crime With Intent To Terrorize,” 422(A) PC – against immediate family or any other person who regularly resides in the household, 422.6(A) PC – a person, whether or not acting under color of law, shall not, by force or threat of force, willfully injure, intimidate, interfere with, oppress, or threaten any other person in the free exercise or enjoyment of a right or privilege secured by the Constitution or laws of this state, and 242 PC – battery. Case Number: 26-7027 and Incident Number: 2607270189. However, the arrest is not included in the list on the APD CitizenRIMS website.
Whitaker also shared that the incident is unrelated to what occurred on July 30, 2026, when the Antioch Police Department served a search warrant at a residence in the 4000 block of South Royal Links Circle as part of an ongoing investigation involving possible homemade explosive devices.
Investigators are examining whether today’s incident is connected to the recent social media attention surrounding the July incidents. While APD recognizes the strong public reaction, retaliation and vigilante acts are not an acceptable substitute for the criminal justice process. The July matters were investigated by APD and are being addressed through the appropriate legal processes.
Members of the public who have information or evidence are encouraged to provide it to law enforcement rather than take matters into their own hands. Harassment, threats, trespassing, property damage, or acts of violence directed at any person or residence may constitute separate criminal offenses and will be investigated accordingly. Such actions can also place uninvolved neighbors, including children and pets, community members, and first responders at risk.
Anyone with information about today’s incident is asked to contact the Antioch Police Department Investigations Bureau at (925) 779-6926 and reference Case No. 26-7784. Tipsters may remain anonymous.
Because today’s investigation remains active and the July criminal case is pending, APD is limiting the release of additional details that could compromise either matter. Additional information will be released when appropriate.
