From a New York Times obit by Richard Sandomir headlined “Arnold Diaz, Who Reported on New York Swindlers, Dies at 74”:

Arnold Diaz, a brash investigative reporter at three New York City television stations who brought righteous passion to segments that shamed con artists, business owners, scammers, government bureaucrats and others who ripped off consumers, died in Greenwich, Conn.

Mr. Diaz wanted not only to resolve victims’ problems but also to embarrass the malefactors for their misdeeds. He confronted them, chased them and shoved microphones in their faces in search of answers.
