SEATTLE (AP) — Federal agents have made more arrests in a drug pipeline that stretches from Mexico to north of Seattle in Snohomish County.

Authorities seized what they believe to be 16,000 fentanyl pills, 30 pounds of meth and 6 pounds of heroin, according to the Department of Justice.

Eight people, including five from Snohomish County, were indicted Wednesday in U.S. District Court in Seattle. The Justice Department says most of the drugs were seized from a Mexican citizen living in Woodinville who was stopped by law enforcement in Seattle on Oct. 25.
