This photo of JPMorgan Chase chief Jamie Dimon holding up his fists ready to throw down? It's not just for show. If Chase loans you money to, say, buy a Mercedes SUV and you don't pay the bank back, Dimon will use any means necessary to insure you follow through. At least that's what a man named James Ricobene claims, who is now suing JPMorgan Chase for allegedly resorting to dirty tactics to collect the collateral on a car loan. Ricobene says Chase hired a shady collection outfit to harass him and posted a threatening message on his daughter's MySpace page vowing to report the 2007 Mercedes GL450 as stolen and put him in jail for two years if he didn't come up with the goods. We can't imagine Dimon would condone such unethical conduct, if only because he probably doesn't even know what MySpace is. But Ricobene probably shouldn't have been in this position to begin with, especially since he happens to be the president of a company called Cash Flow Consultants Inc. The full suit after the jump!
