A Uniondale woman scammed immigrant clients by selling them fraudulent car insurance policies, according to authorities, who arrested her Friday on multiple felony charges.

Prosecutors identified the defendant as Erika Garcia Cruz, 37, after her Hempstead arraignment on felony charges of grand larceny, scheme to defraud and criminal possession of a forged instrument.

The Nassau County district attorney's office said Cruz, an unlicensed insurance broker who worked at Ismarlin Multiservice in Hempstead, sold car insurance policies to undocumented immigrants and charged them double the actual costs.

Authorities also have alleged Cruz fraudulently obtained the policies using fake Virginia addresses that meant lower insurance premiums.

Prosecutors said Cruz had control of the company, which wasn't registered with the state and is no longer operating.

They also alleged that she made tens of thousands of dollars in the scheme.

Prosecutors said a judge remanded Cruz to jail and that the Legal Aid Society represented her in court. The agency doesn't comment on cases.

Authorities said the case started with a tip to the district attorney's office's Immigrant Fraud Investigations Office hotline, and that the investigation is continuing.
