A Brooklyn federal judge has sentenced Richard Luthmann, a Staten Island attorney who once challenged opposing counsel to a “trial by combat,” to four years on fraud and extortion conspiracy charges for his role in an illegal scrap metal scheme.

U.S. District Judge Jack B. Weinstein of the Eastern District of New York handed down his sentence Monday afternoon, after hearing arguments from prosecutors and defense counsel last week. In addition to prison time, Luthmann was ordered to pay $500,000 in restitution and $130,000 in forfeiture.
