5:30 pm UPDATE
On January 6, 2026, at approximately 8:16 a.m., Antioch Police Department officers responded to a report of a family dispute at a residence in the 50 block of East 6th Street.
Upon arrival, officers contacted a 25-year-old woman and determined she was the victim of a felony assault. The woman was transported to a local hospital for treatment of non-life-threatening injuries.
Officers attempted to make contact with the suspect, identified as 31-year-old Matthew Britt.
Britt barricaded himself inside the residence and refused to exit. Officers learned Britt was possibly armed with a knife and had an extensive criminal history involving violence and evading law enforcement.
Due to the circumstances, the Antioch Police Department SWAT Team and Crisis Negotiations Team were deployed. After several hours of negotiations and de-escalation efforts, Britt voluntarily surrendered without incident.
Britt was uninjured and was evaluated by medical personnel at his request. He was subsequently booked into the Contra Costa County Jail on felony assault charges and is awaiting criminal filing by the Contra Costa County District Attorney’s Office.
