NEW YORK—Martin Shkreli has been sued in New York by a digital art collective that said it paid $4.75 million for a one-of-a-kind album by the hip-hop group Wu-Tang Clan, only to learn that the convicted pharmaceutical executive made copies and is releasing the music to the public.
Mr. Shkreli paid $2 million in 2015 for “Once Upon a Time in Shaolin,” and gave it up to partially satisfy a $7.4 million forfeiture order after his 2017 conviction for defrauding hedge fund investors and scheming to defraud investors in a drugmaker.
