Now that Martin Shkreli has been arrested, he apparently thinks he's thug and flexed his muscle in a kind of super creepy diss video targeted at Ghostface Killah. The footage was filmed after the Wu-Tang member called the "pharma bro" a "shithead" to TMZ last week because he wouldn't share Once Upon a Time in Shaolin (a one-of-a-kind album Shkreli bought for $2 milliom) with the public.

In the video, good old entitled Martin threatens Ghostface that he will erase all of his parts on the album if the MC doesn't write him "a written apology from the heart." "At the end of the day, I'm very sorry for you," he said. "You're an old man—an old man that's lost his relevance, and you're trying to claim the spotlight from my spotlight. That's not going to work, Ghost—Dennis. In fact, I think that if you ever say some dumb shit again, this album, this Shaolin, I'm going to erase all your shit from this album. I'm going to erase you from the record books."

As if the video wasn't enough, Shkreli also took to Twitter with his threats. Read those and watch the full video below.

As mentioned in my video, I expect a written apology, @GhostfaceKillah. At least 500 words, no grammatical errors and Shaolin stays intact.

A @GhostfaceKillah response tomorrow evening. Don't cry, Ghost. All rap careers come to an eventual end. Long time coming, motherfucker.
