Identity theft is a serious on-going problem for a city that generally doesn't fall for scams easily. So it's reassuring to see that police have caught Iguosade Osahon, 28, of Brooklyn, who is accused of stealing 750 identities and more than $500,000 from victim accounts. He pleaded not guilty today to 147 counts of of identity theft, grand larceny, and other charges, and is being held in lieu of $150,000 bail. Osahon allegedly stole victims' personal data via illegal online data traffickers; Manhattan DA Cyrus Vance said Osahon subsequently blew through the cash by buying Tiffany jewelry, Rolex watches, and luxury goods from Louis Vuitton and Bloomingdale's. But at least he's keeping his humor about him: As cops were arresting him, he leveled with them, "What can I say? You've got me by the balls."
