The letter identifies specific assets to be forfeited, including the famous "Once Upon a Time In Shaolin", the only extant copy of a Wu Tang Clan album Shkreli purchases and famously bragged about on social media.
After buying the single-release album from the legendary NY hip hop group and agreeing at the time not to release it commercially for at least 88 years, the infamous businessman entered into a feud with Wu Tang's Ghostface Killah, who called Shkreli a "s**thead" when he learned who had purchased the record, according to outcome of Sound.
In 2015, the ex-Turing CEO was heavily criticized for raising the cost of the life-saving drug Daraprim by 5,000 percent. He is being held at the Metropolitan Detention Center in Brooklyn awaiting sentencing and could serve up to 20 years.
TMZ spoke to his attorney, Ben Brafman, who told them, "Our position is clear".
Prosecutors on Thursday asked Brooklyn Federal Court Judge Kiyo Matsumoto to seize $7.4 million in assets from Shkreli, the former pharmaceutical executive and hedge fund manager who was convicted in August of defrauding investors.
Later, the album became the focus of two multi-million-dollar lawsuits and, additionally, allegations that it might not be an actual Wu-Tang Clan album after all.
Prosecutors say Shkreli's assets subject to forfeiture also include an Enigma code-breaking machine from World War II and an unspecified Picasso.
Shkreli's counsel, private attorney Benjamin Brafman, could not be reached for comment.
Shkreli was convicted of securities fraud and conspiracy in August, and is now in a maximum security prison awaiting sentencing.
Greebel's defense hinges on casting the lawyer as an unwitting pawn of Shkreli's machinations.
