A years-long nightmare is finally over for the 20 families scammed into buying fraudulent condos in Bay Ridge. On Friday, Attorney General Tish James’s office announced that $4.2 million, plus a decade of interest, will be returned to Chinese immigrant families defrauded by developer Steven Wu. “This order returns money to the families Wu cheated and ensures he can never again exploit New Yorkers through fraudulent real estate schemes,” James said in a statement.
