Prescription drug hoarder and collector of rare Hip Hop Martin Shkreli bagged about still running his business from a federal pen in a recent Wall Street Journal article.

Now he's paying for that flex.

Shkreli, who is serving seven years for securities fraud and conspiracy, mentioned an illegal phone and secret Twitter page when he boldly claimed he would leave Fort Dix richer than when he entered.

Having that type of technological contraband is a big no-no, and now two sources close to Shkreli have told Forbes that their boy has been placed in solitary confinement for his stunt. Fort Dix wouldn't confirm that Shkreli was in the hole, but did confirm that the claims he made in the Journal article were "under investigation."
