Chicago ? A reputed mob enforcer who has been the focus of a nationwide manhunt since federal prosecutors unsealed racketeering-murder charges against the alleged top echelon of the Chicago underworld was arrested Friday, the FBI announced.

Frank “The German” Schweihs, 75, was captured without incident when agents swooped down on an apartment he had recently rented in Berea, Ky., a hilly area 40 miles south of Lexington.

Schweihs was one of two defendants who slipped away in April just before federal prosecutors unveiled the long-sealed indictment against reputed Chicago mob boss James Marcello and 13 others in the FBI’s Operation Family Secrets investigation.

FBI agents still are hunting Joseph “Joey the Clown” Lombardo, 76, known as one of the senior figures in the Chicago mob.

The indictment charges that Chicago hoodlums and mob associates conspired in at least 19 deaths, including that of Tony “The Ant” Spilotro, once known as the Chicago Outfit’s man in Las Vegas, and his brother Michael.
