FBI agents arrested Trenton, New Jersey, mayor Tony Mack Monday morning on corruption charges, as part of an investigation dating back to 2010.

According to the Trenton Times, Mack, along with his brother Ralphiel and campaign contributor Joseph "JoJo" Giorgianni, were involved in a plan to get $119,000 in bribes in connection with the building of a parking garage on city property.

WNBC-TV reported that all three men were taken to the FBI office in Hamilton, New Jersey for processing prior to appearing in federal court.

"This is not a surprise," former campaign aide Jerell Blakley told the station. "A lot of people in Trenton were of the opinion -- not of if, but when."

WPIX-TV reported that charges against the three men will be announced at a news conference at 11:30 a.m. Monday morning.

According to the criminal complaint filed against the trio Monday, authorities used both wire taps and cooperating witnesses to build their case, with Ralphiel Mack serving as an intermediary for money Giorgianni received for the garage project. The complaint said they had already received $54,000 in cash during the investigation, and expected to get $65,000 more; Giorgianni allegedly referred to the payments as "Uncle Remus."

Investigators had raided Mack's home in July and also visited Ralphiel Mack and Giorgianni at home. Giorgianni, who had donated $4,600 to Tony Mack during his mayoral campaign two years ago -- more than twice the individual contribution limit -- was convicted for sexually assaulting a 14-year-old girl in the back of his sandwich shop in 1992. At the time, WNBC-TV said, Mack's office in City Hall was also searched.

The Times also reported that Giorgianni has been charged in a separate case involving distribution of prescription drugs from his restaurant, though authorities say no city personnel has been charged in that case.

Update: WNBC posted video Monday morning of Mack being led into custody, which can be seen below.
