Federal officials say about 16 of those arrested are from Long Island, including former Suffolk County police officer Robert Dito, who is accused of tipping off gambling clubs about impending raids.

U.S. Attorney General Eric Holder said during a news conference Thursday the defendants include high-ranking members of the Gambino and Colombo crime families from New York and New Jersey and the reputed former boss of organized crime in New England.

Holder said the charges cover decades worth of offenses, including hits to eliminate perceived rivals, a killing during a botched robbery and a double shooting in a barroom dispute over a spilled drink.

According to the indictment, mafia members were running gambling operations at several locations on Long Island, including Castle Collision in Westbury.

Authorities say the investigation was aided by informants who recorded thousands of conversations by suspected mobsters. More than 700 law enforcement officers from federal, state and local agencies took part in the operation.

Holder said the arrests dealt a major blow to organized crime, but the fight is far from over.

"We are committed and we are determined to eradicate these criminal enterprises once and for all and to bring their members to justice," Holder said.
