Report to police/action fraud. Ensure you copy all his details, that way an previous he has will come up, and potentially will be easier to track/obtain evidence.
I've a friend who works in this area although more high end stuff, see what he thinks. Only problem there is so much low level fraud, that unfortunately there simply isn't the resouces to cope, saying that if he's known and prolififc, it's a countdown til his next arrest.
