A former top aide to indicted state Sen. John Sampson was sentenced to three years in prison Friday for tax fraud and for conspiring with his former boss to steal $100,000 from the state Democratic Senate Campaign Committee, authorities said.

Melvin Lowe, 53, scammed the money out of the DSCC in 2010 by getting a printing vendor to send the committee a fake invoice and then forward $75,000 of the cash to himself.

Manhattan US Attorney Preet Bharara called the case “ another example of a political figure in New York state putting his own personal greed ahead of the public’s trust.”

Sampson, who was re-elected to his seat in Brooklyn, still faces eight federal counts.
