Authorities, including the FBI and local police task forces, zeroed in on seven mob families in New York, New Jersey, and Rhode Island, arresting over 100 people on Thursday with charges ranging from racketeering and extortion to murder. The raid, said to be the largest mob sweep ever conducted by federal authorities, began deep into the night and ended around 8 a.m., as everyone from small-time bookkeepers to high-level mob figures were sent to the clink. According to sources, more than two dozen made men in New York's five crime families, and the families in New Jersey and New England, were among those booked by authorities. Several of the men arrested were charged with murders, with some dating as far back as the 1980s and 1990s. Attorney General Eric Holder announced the charges at a news conference Thursday morning in Brooklyn.
