Alec Baldwin, Sally Field and tennis star Steffi Graff are among a long list of celebrities whose confidential tax files were reportedly uncovered illegally by an Internal Revenue Service (IRS) tax examiner.
John Snyder was arrested in Kentucky on Thursday after allegedly peering into the financial records of over 200 celebrities and professional athletes.
Snyder, 56, has been employed by the U.S. government agency since 1981.
He faces one year in jail and $250,000 in fines if he is charged.
