The son of Sen. Tom Libous pleaded not guilty to six federal counts of filing false tax returns and obstruction and was arraigned on $50,000 bail.

Matthew Libous is accused of using the under reported income from a minority stake in Wireless Construction Solutions for a variety of personal uses, including iTunes downloads, casino trips, tanning, spa treatments, a gym membership and even an Internet data site, according to the indictment unsealed Monday.

Between 2008 and 2011, Matthe Libous is accused of failing to report more than $200,000 in income to the IRS.

Sen. Tom Libous faces one count of making a false statement to the FBI stemming from an investigation in whether he arranged for his son to receive a job at a prominent Westchester COunty law firm paid for by a lobbying organization.

“As alleged, Thomas Libous took advantage of his position as Senator and Chairman of the Transportation Committee by corruptly causing lobbyists, who wanted Libous’s influence to benefit their clients, to funnel money through a law firm to his son where Libous has gotten his son a position,” U.S. Attorney Preet Bharara said in a statement. “He then tried to cover up his corrupt conduct by lying to FBI Agents about his knowledge of his son’s arrangement with the firm, as the Indictment describes. Public servants should serve the public first, not themselves and their families. This Office will continue to pursue elected officials who attempt to take corrupt advantage of their positions.”
