Trenton Mayor Tony Mack has put two city rental properties up for sale as a federal probe of his administration heads to a grand jury.

The Times of Trenton reports  that Mack has listed a fire-damaged home on Hampton Ave. and his boyhood home on Tioga street as "for sale by owner" on the real estate web site owners.com.

Separately, City Hall and the current homes of Mack, his brother and a campaign donor were raided by the FBI in July.

Documents obtained by The Times of Trenton showed investigators were trying to find evidence dealing with fraud, extortion, money laundering and city contracts.

Mack has denied any wrongdoing and it's not clear if he's hired an attorney.
