A major drug bust in Klamath County resulted in 20 arrests when 14 homes were searched Wednesday in the culmination of a months-long investigation.

The bust was the first major case of new multi-agency Drug Crimes Strike Force that includes Klamath Falls police, Klamath County Sheriff's Department and the Oregon Department of Justice, the Oregon attorney general's office said in a news release on the operation. A $1.5 million federal grant secured by Oregon Attorney General John Kroger in 2009 funds the team.

The investigation initially focused on a network of illegal manufacturing, sales and possession of methamphetamine, marijuana and prescription drugs in the Klamath Falls area, the state Department of Justice press release said. The investigation expanded to include weapons charges, theft, possession of stolen property and probation and parole violations.

The team on 47 officers served search warrants Wednesday morning at locations scattered across Klamath Falls and 20 people were arrested. All face drug charges and some also face charges related to homemade bombs found at one home.

The Oregon State Police Bomb Squad from Central Point helped at a home where suspected destructive devices were located.

Authorities said additional charges and more arrests are expected.
