A federal grand jury has indicted the mayor of New Jersey's capital city on corruption charges.

Trenton Mayor Tony Mack, his brother and an associate are accused in an eight-count indictment of extortion, bribery, and mail and wire fraud.

New Jersey's U.S. attorney's office says the charges are related to an alleged scheme to accept $119,000 in bribes in exchange for Mack's influence in the development of a garage on city-owned land.

The indictment was handed up Thursday in Trenton.

Mack has continued in his position despite a no-confidence vote by the Trenton City Council after his September arrest.

His attorney has said Mack is innocent. An attorney for his brother, Ralphiel Mack, says his client is not guilty.
