OMAHA, Neb. (AP) — An Omaha man who prosecutors say ran a sports bookmaking operation has pleaded guilty to tax evasion.

Forty-three-year-old Todd Bartusek faces up to five years in federal prison when he’s sentenced on Jan. 9. He entered his plea earlier this month.

Prosecutors say an Internal Revenue Service investigation determined that Bartusek worked as a bookie from 2007 through 2010 and didn’t report his income. Prosecutors say Bartusek owes the IRS nearly $257,000 in taxes on that unreported income.
