Federal authorities arrested Trenton, N.J., Mayor Tony Mack and more than half a dozen other people early Monday in connection with an ongoing corruption probe, NBC 4 New York has learned.

Mack faces federal charges including conspiracy to obstruct commerce by extortion. Joseph "JoJo" Giorgianni, a top campaign contributor, and six others were also taken into custody. Information on their attorneys wasn't immediately available. Specific charges against the suspects are expected to be outlined by Paul Fishman, the U.S. Attorney for New Jersey, later Monday.

Mack and the others arrested Monday were brought to the FBI office in Hamilton for processing and are scheduled to appear in federal court.

REST OF IT

The arrests are the latest development in an ongoing federal investigation into alleged corruption within Mack's administration, which has been marked by accusations of nepotism and reckless spending. In July, FBI agents searched offices in Trenton City Hall a day after raiding the mayor's home. They also searched the home of his brother, Ralpiel Mack, and that of Giorgianni.
