A man and a woman from Norwich are arrested as a result of a investigation into narcotics sale and possession. Police say a search warrant was executed Thursday at a State Street apartment and a quantity of methamphetamine was discovered that officers say was being sold. In addition to the drug charges Todd Diamond Jr., and Brittany Dunagan, face child welfare endangerment charges because a 17-year-old was in the apartment when the drugs were being sold. Bail for Diamond and Dunagan was set at $10,000 and they are due in court on Tuesday.
