FBI finally gets the goods on the last don

A FABLED, 20-year-old FBI undercover operation resurfaced to shock the US underworld this week.

It led to the arrest of Joseph Massino, the reputed boss of the Bonanno crime family and, feds say, the last New York city boss left.

FBI agents arrested Massino, 60, early on Thursday morning at his home on 84th Street in Howard Beach, Queens, on racketeering conspiracy, murder and other charges.
