CUMMING — Authorities say they found about two kilos of heroin — the largest Forsyth County bust of its kind in recent memory — Wednesday afternoon at a north Cumming home.

The operation also resulted in the arrest of one man, described only as in his 30s. It came about after Forsyth County Sheriff’s Office received information about a possible distribution house being set up a few days ago.

A distributor can sell between 4,000 and 32,000 doses of heroin — depending on how it is cut — from the amount that was found, said Doug Rainwater, a spokesman for the sheriff’s office.

The seized heroin is thought to be 90 percent pure and has an estimated street value of between $150,000 and $250,000, authorities said.

“This just shows that all of our narcotics deputies, and all of our deputies, feel strongly about our community,” said Sheriff Duane K. Piper, “because we worked very hard in the past three days on this.”

Rainwater said the alleged “major distributor,” who is being held without bond at the Forsyth County Detention Center, apparently moved to Cumming "within the past several months" to “establish a foothold in the north Atlanta area.”

For the time being, the sheriff’s office is withholding the street address, which is in the city limits, and suspect’s name.

Officials did say, however, that the man did not live in Georgia prior to last year.

Rainwater could not say whether more arrests were expected, only that the investigation is continuing.
