NEW YORK — For 10 months, rumblings, lawsuits, law enforcement raids and mounting allegations of widespread sexual abuse had surrounded Sean 'Diddy' Combs. The business empire, cultural cachet and fatherly image he had cultivated in the decades since he became a hot young hip-hop mogul in the 1990s had begun to erode.

On Tuesday, those ripples became a wave with the unsealing of a sweeping indictment alleging years of sex trafficking and conspiracy, to which he pleaded not guilty before a federal magistrate ordered him jailed without bail as he awaits trial.
