Embattled former pharma CEO Martin Shkreli's legal troubles deepened Tuesday when the poster child for greed was sued for copyright infringement in connection to the $2 million Wu-Tang Clan hip-hop album he bought last year.

Shkreli is the founder and former CEO of Turing Pharmaceuticals who became reviled for increasing the price of a life-saving drug by more than 5,000 percent last year. He also faces unrelated federal criminal charges that he allegedly defrauded investors, and he has invoked his Fifth Amendment right against compelled self-incrimination before congressional panels probing the price of pharmaceuticals.

The latest brouhaha concerns his exclusive $2 million purchase of the "Once Upon a Time in Shaolin" album, the only copy Wu-Tang Clan produced. The 32 year old said he bought the album to "keep it from the people." Packaging for the album includes a 174-page book with all sorts of writings, pictures, and drawings. In that book are portraits of band members created by a New York artist named Jason Koza, who claims in a new federal lawsuit that he never authorized their reproduction.

The copyright infringement suit accuses band leader Robert "RZA" Diggs of allegedly including Koza's art and names Shkreli for allegedly allowing three Koza works depicting Wu-Tang Clan members Inspectah Deck, Ol’ Dirty Bastard, and Raekwon to be included in a January Vice.com article about the album.

In late 2013 and early 2014, Mr. Koza created portraits of each original member of the Wu-Tang Clan and submitted digital images of the portraits to the WuDisciples.blogspot.com website for public display. Mr. Koza was happy when his work appeared on the website and went about his life for the next approximately two years, continuing to create more original works of art. On January 29, 2016, Mr. Koza became aware of a news article about a new Wu-Tang Clan album titled “Once Upon a Time in Shaolin,” the sole copy of which was reportedly sold to Martin Shkreli for approximately $2 million. The album included a 174-page book, which contained copies of Mr. Koza’s Wu-Tang Clan member portraits. This story only has one problem: Mr. Koza never granted a license for his works to be copied or displayed anywhere other than the WuDisciples.blogspot.com website.

Meanwhile, the infringement allegations aside, it was revealed during a hearing before the House Committee on Oversight and Government Reform last week that after Turing Pharmaceuticals raised the price of the decades-old drug Daraprim from $13.50 a pill to $750 last fall—leaving some patients with $16,000 co-pays—Turing executives handed out six-figure bonuses, spent thousands of dollars on a lavish yacht party, and paid a public relations firm to help them shine their tarnished reputation.

Shkreli resigned as Turing's chief executive in December, shortly after being indicted on fraud charges for allegedly running a Ponzi-like scheme with two former hedge funds and swindling another former pharmaceutical company, Retrophin, out of millions of dollars. Shkreli, who appeared at that House hearing last week, invoked his Fifth Amendment right against compelled self-incrimination and did not testify. He later called lawmakers at the hearing imbeciles.

Shkreli's attorney, Benjamin Brafman, defended his client.

"In short, the intent of the committee, by insisting on Shkreli's personal appearance, was to embarrass him by forcing him to publicly invoke his Fifth Amendment privilege because of an unrelated pending indictment," he said. Shkreli has said he is not guilty of the charges.
