BROOKLYN - Authorities have indicted a former stockbroker from Brooklyn for allegedly scamming thousands of dollars from investors. Officials say Boris Shteyngart, 24, operated a Ponzi scheme using forged checks beginning in 2009. He would reportedly ask investors to make their checks out to "BORI," which he claimed stood for the Bank of Rhode Island. Once receiving the check, officials say he would add an "S" the end of "BORI," and would cash the check under his first name. Investigators say Shteyngart ran the scam from his Sheepshead Bay apartment and would call prospective investors from all over the country. One of his alleged victims was an 84-year-old Queens resident, who has now lost most of his life-savings, close to $10,000.
