Miami-Dade Crime Stoppers doles out cash for tipsters who turn in criminals.

But one of their own -- a Miami officer taking tips -- used the inside information to rip off thousands of dollars in reward money, authorities said.

Officer Wayne Fortella, an 11-year Miami police veteran, was charged Wednesday with wire fraud and conspiracy in Miami federal court. Two of his friends, who allegedly collected the Crime Stoppers payments at Wachovia banks, were also charged. One is at large.
