Assets seized in connection to an illegal sports betting ring in Maine makes this year's total collected by the U.S. attorney's office almost $20 million.

The Bangor Daily News reports Stephan Mardigan pleaded guilty in May 2018 to illegal gambling, money laundering and filing a false tax return.

In January the 63-year-old was sentenced to 15 months in prison, and was ordered to forfeit about $13 million in property as well as over a million dollars in cash.

The U.S. attorney's office in Maine says last fiscal year it collected nearly 20 million. The previous year it collected about 4 million.
