Officers responded to Gulf Drive, just south of Sequoia Drive, at 12:16 p.m. to find what appeared to be a small improvised explosive device resting on the street.
As a safety precaution the neighborhood was cordoned off and nearby residents were asked to shelter in place. The Yolo County Bomb Squad and the Bureau of Alcohol, Tobacco, Firearms and Explosives Task Force responded to the scene and rendered the device safe, according to police.
This is the second incident where an explosive device was found in this neighborhood. On Aug. 28 a device was discovered on Gulf Drive near Redwood Drive -- about a block away from Friday's incident.
Both devices appear to be constructed similarly and are believed to be related to each other, police said.
Anyone with information regarding either incident is asked to call Fairfield police at (707) 428-7300 or Solano Crime Stoppers at (707) 644-STOP.
