A fourth arrest has been made in connection with a meth lab in Ellsworth. Drug agents spent the day on Hancock Street yesterday.

WABI-TV reports that Karen Ward, age 51, was arrested today and charged with drug trafficking. Ward is the tenant in the apartment where DEA agents say they found evidence of a meth lab and a significant amount of the drug.

Three others were arrested in connection with this case. This is the second meth lab disassembled by MDEA this week. The first was in Newfield on Tuesday.
