From the New York Times:

Federal and state authorities early Thursday began rounding up scores of accused organized crime figures on a series of indictments charging murder, racketeering, construction extortions and other crimes in the largest such sweep in recent memory, law enforcement officials said.

About 80 people — among them the entire Gambino family hierarchy and reputed figures from the Genovese and Bonanno families — are named in two indictments, along with union and construction industry officials, the law enforcement officials said.

By about 10 a.m., 52 people were already in custody, including the family’s acting underboss, Domenico Cefalu, and consigliere, Joseph Corozzo, the officials said. The acting boss, who prosecutors identified as John D’Amico, known as Jackie the Nose, was not yet in custody and several officials said he was believed to be on vacation.

The Gambino, Genovesse, and Bonanno families are part of the 5New York Crime Families.  The other two are the Lucchese and Colombo families.
