PITTSFIELD — Two people in the Berkshires have been arrested as part of a three-month investigation into a nationwide organized fraud scheme, according to the Berkshire District Attorney's Office.

The two individuals, who were not named, played a major role in the organized fraud, larceny and conspiracy ring, the DA's Office said in a release. Individuals and businesses in the Berkshires received proceeds from the multistate scheme.

On Monday, five search warrants were executed at three locations in the Northern Berkshires. Investigators intercepted a "significant amount" of money shipped to these locations and returned it to the victims, the release said. Law enforcement also identified many of the criminal conspirators involved, their locations, the delivery methods and the location of the suspected call center initiating the fraud.

"I thank the State Police Detective Unit, Adams Police Department, and all of our partner agencies for their dedicated work investigating this complex scheme. This sophisticated conspiracy ring defrauded vulnerable people throughout the entire United States," Berkshire District Attorney Andrea Harrington said in the release. "Criminal enterprises steal millions of dollars from vulnerable individuals every year. Our partner law enforcement agencies and my office are committed to protecting vulnerable populations from organized fraud conspiracies."

The investigation is ongoing, and Harrington has scheduled a news conference for Tuesday afternoon to discuss the case, following the arraignments of the two individuals involved.

"We remind Berkshire County residents to remain vigilant in protecting themselves from elaborate telephone scams in which an unknown caller seeks to alarm, panic and distress to coerce the recipient to transfer money to the caller," the release said.
