A second-generation employee of Bernard Madoff who was one of the earliest government cooperators after the massive Ponzi scheme was revealed was sentenced Wednesday to nine months of home detention.

Eric Lipkin, who said he “cannot apologize enough” for his crimes and the impact of the fraud on thousands of investors, was sentenced by Southern District Judge Laura Taylor Swain. She said Lipkin had made significant amends through years of cooperation to earn a substantial reduction from what could have been a life sentence.
