(KRON) — Four people were arrested after police found multiple firearms during the execution of two search warrants across the Bay Area on Friday, according to a press release from San Francisco Police Department.

Just before 6 a.m. on Friday, SFPD officers with the Community Violence Reduction Team (CVRT) working with SFPD’s Special Operations Group (SOG), Fairfield Police Department, and Oakland Police Department, completed a search warrant on the 2800 block of Bay Tree Drive in Fairfield and the 7000 block of MacArthur Boulevard in Oakland.

Throughout an earlier investigation, police say that they determined these residences were connected to a wanted fugitive as well as a convicted felon who was in possession of illegal firearms.

As SFPD walked towards the Oakland residence, one of the suspects, Emonie Bailey, 27, of Fairfield, fled the scene on foot. Bailey was tracked down and taken into custody. Three more suspects, Harold Hollis, 27, of Oakland, Darell Everette, 22, of Vallejo, and Skyy Winnfield, 20, of San Francisco were also located inside of the residence. All three people were detained for further investigation.

Investigators found multiple loaded, high-capacity assault weapons, magazines, and unfired cartridges inside of the Oakland home. All of these items were seized by police. Using the evidence found in the course of the investigation, SFPD arrested Bailey, Hollis, Everette, and Winnfield.
