SPOKANE, Wash. (AP) — A task force of federal, state and local law enforcement officers arrested 18 people in eastern Washington and northern Idaho for drug-related charges.

More than 100 officers were involved in Thursday's arrests, which occurred in the Spokane, Yakima and Post Falls, Idaho, areas.

The Spokane County Sheriff's Office says four additional people are still being sought.

The arrested people will face an array of charges in federal court for conspiracy to distribute cocaine and methamphetamine. The arrests are the culmination of a two-year investigation by the Spokane Regional Safe Streets Task Force.
