The announcement this week has prompted a separate review by the Daily News of dozens of articles the writer contributed to the tabloid newspaper.
The Voice's editor, Tony Ortega, says Rob Sgobbo invented a college student and a U.S. Government Accountability Office spokesman quoted in a Wednesday article. Both organizations contacted the Voice and said the people didn't exist.
The writer hasn't returned a telephone message left by The Associated Press on Friday.
The Daily News says the writer said he hadn't fabricated any information in pieces he wrote for it. But it says it's reviewing his stories.
