SOUTH PARIS — Court records reveal few details about a drug conspiracy charge brought against a state-licensed clinical counselor who was one of 15 people arrested this week and accused of running a major heroin distribution ring in Oxford County.

The counselor, 54-year-old Gregory Ford of Scarborough, was arrested Tuesday after being indicted last week by an Oxford County grand jury on a charge of conspiracy to commit aggravated trafficking in heroin.

The drug ring smuggled Mexican heroin through a supplier in Lowell, Massachusetts, to dealers in Maine, who had imported and distributed nearly 18 pounds of heroin since 2013 in various locations throughout Oxford County, officials said. That much heroin represents about 80,000 doses with an estimated street value of $3.2 million, they said.

A copy of Ford’s indictment in Oxford County Superior Court in South Paris states that he committed the conspiracy sometime between Feb. 1 and April 17, 2015, with one or more of the other individuals arrested in the case.

The indictment further states that he “did agree with Del Hathaway, and/or Cameron Gervaius, and/or Matthew Ross, or one or more others to engage in or cause the performance of that conduct, by taking substantial steps toward the commission of that crime by using text or cellular communications for the purpose of distributing heroin and, in fact, by distributing heroin within the State of Maine.”

Since Ford was indicted before his arrest, authorities were not required to file a police report or affidavit to support the charge against him. Nothing else about the accusations against him was including in his case file.

Ford, who did some substance-abuse counseling as part of his profession, received a conditional counseling license from the state in 2008. His current license expires on Jan. 31, 2017, according to state records.
