NEW YORK — Federal agents dealt another major blow to New York’s five Mafia crime families by arresting more than 100 suspected mobsters throughout the Northeast on charges including murder, extortion and narcotics trafficking.

The FBI said most of the arrests were made this morning. Many were in Brooklyn, but they also occurred throughout New York City and in New Jersey and New England.

The takedown was the result of multiple investigations. Federal probes aided by mob turncoats have decimated the families’ ranks in recent years and have resulted in lengthy prison terms for several leaders.
