Bossier police want businesses that serve as locations for Western Union to know about a scam that's already hit three such local businesses.  Somebody calls the business claiming that they're from Western Union and need to test the store's terminal.  The caller then tells the person at the business to enter certain information into the terminal along with a dollar amount.  It turns out not to be a test but an actual funds transfer and it's hit the three local businesses that have been scammed already out of about $900 each.  Police have informed Western Union about the scam and they're urging any business that might be contacted in this way to try to get contact information from the caller -- then hang up immediately and notify Western Union.
