Nine people were arrested, a number of firearms were seized and drugs were confiscated following a months-long investigation into gang activity in Contra Costa County, according to officials.
The investigation was focused on a gang in East Contra Costa County believed to be involved in illegal firearms dealing, according to officials.
Following the investigation, eight search warrants were performed last week in the East Bay cities of Pittsburg, Antioch and Bay Point.
Officers found an AK-47 assault rifle, three handguns, high-capacity magazines, cocaine and other pills, officials said.
The nine arrestees were booked into the Martinez Detention Facility, according to officials. The charges for those arrested include conspiracy, gang and narcotics violations, and a slew of weapons charges.
The Contra Costa County Anti-Violence Support Effort spearheaded the investigation and was assisted by a number of federal, state and local agencies.
