Caught: "Whitey" Bulger nabbed after 17 years on the lam

Bulger, 81, has been the subject of several books and was the inspiration for “The Departed,” a 2006 Martin Scorsese film staring Leonardo DiCaprio, Matt Damon and Jack Nicholson.

Bulger fled Boston in late 1994 as federal agents were about to arrest him in connection with 21 killings, racketeering and other crimes that spanned the early 1970s to the mid-1980s.

He was arrested by the FBI inside a building without incident, according to the sources, who asked not to be named because they were not authorized to speak on the matter.
