A 19-year-old Rockland woman remained in jail this morning after being arrested Sunday night on charges of selling Ecstacy tablets.

The Maine Drug Enforcement Agency’s midcoast regional task force arrested Sadie Knight following a month-long investigation into the sale of Ecstacy in the Rockland area. Officers stopped Knight and allegedly found 63 Ecstasy tablets worth $1,600 on the street, $300 cash and an unloaded .22 caliber handgun hidden in her vehicle, police said.

Knight was taken to Knox County Jail where she was being held on $2,500 bail.
