State corrections officials said Lillo Brancato Jr. was paroled Tuesday and released from Hudson Correctional Facility at 9 a.m.
Brancato has served less than 10 years for his role in a botched burglary that led to the death of New York City police officer Daniel Enchautegui.
Brancato was acquitted of murder, but found guilty of felony attempted burglary. His co-defendant was convicted of murder and sentenced to life in prison without parole.
Brancato portrayed Matthew Bevilaqua, a young mobster on The Sopranos.
He also played Robert De Niro's son in the 1993 film, 'A Bronx Tale.'
