The disgraced former city manager of the Los Angeles suburb of Bell has agreed to plead guilty to charges that he filed a false federal income-tax return to illegally reduce his tax liability.

Federal prosecutors say a plea agreement filed Thursday shows Robert Rizzo agreed to plead guilty to one count each of conspiracy and filing a false federal income-tax return. He faces up to eight years in prison.

The 59-year-old Rizzo admitted he created a corporation to fraudulently claim losses on his income-tax return. The losses to the Internal Revenue Service totaled more than $300,000.

Rizzo pleaded no contest in October to 69 counts of fraud, misappropriation of public funds and other charges for allegedly orchestrating a brazen corruption scandal that drove Bell to the brink of bankruptcy.
