A South Redding couple was arrested Thursday on drug charges. The RPD Special Services Unit served a search warrant at the Farm House Lane home of Jason and Erika Russel. Jason is a registered sex offender. Their home had been raided last May and they were charged with possession of a large quantity of drugs for sale. Police say that since then there have been ongoing tips and complaints about the house. On Thursday officers report again finding the couple in deplorable living conditions with a large amount of Methamphetamine packaged for sale. They were charged with operating a drug house.
