After two people turned themselves in Thursday night, 17 of 23 suspected drug dealers targeted in "Operation Street Sweeper," an effort to get low-level drug providers off Medford's streets, have been arrested, police said.

Jennifer Dani Armstrong, 25, and Susan Jane Smith, 47, turned themselves in at the Medford Police Department Thursday night. Armstrong was charged with possession and delivery of methamphetamine, and Smith was charged with possession and delivery of prescription drugs.

Tony Laverne Lewis, 55, was arrested in the 1200 block of North Riverside Avenue, Medford, late Thursday on charges of possession and delivery of meth.

The arrests capped off a three-month undercover investigation into street-level dealers who repeatedly sell small amounts of drugs, mostly to help feed their own addictions, police said. The effort was the work of the Medford Area Drug and Gang Enforcement Team.

Authorities said they hope that removing some potential sources of drugs will help reduce thefts, burglaries and violent crime by users and improve the livability of the community.

On Thursday about 20 officers spread out across the county to arrest suspected dealers ranging in age from 15 to 55.

The suspects were arraigned in Jackson County Circuit Court Friday. Seven remained lodged in the Jackson County Jail on Friday.
