DAWSONVILLE — Six people were arrested Wednesday for their alleged involvement in what authorities described as a Dawson County-based methamphetamine trafficking operation that reached into Forsyth.

Georgia Bureau of Investigation spokeswoman Sherry Lang declined to discuss specifics, saying only that the group had been under investigation for about 12 months.

“We’re not releasing the names of those involved at his time, because the investigation is ongoing,” Lang said.

The probe was initiated by the sheriff’s office in Forsyth County, where Lang said the Dawson-based operation has networks.

The GBI, along with the sheriff’s offices in Dawson and Forsyth, executed seven search warrants Wednesday.

Two of the three warrants served in Forsyth resulted in arrests, according to the Forsyth County Sheriff’s Office.

The district attorneys in both counties, as well as the Northern District of Georgia U.S. Attorney’s office, were also involved in the effort, Lang said.

The investigation is ongoing and additional arrests are possible.
