Williams, who as the rogue robber of drug dealers Omar Little on "The Wire" created one of the most popular characters in television in recent decades.

Little, a "stick-up boy" based on real figures from Baltimore, was probably the most beloved character among the devoted fans of "The Wire," the HBO show that ran from 2002 to 2008 and is re-watched constantly in streaming.

The Brooklyn-born Williams was also a ubiquitous character actor in other shows and films for more than two decades.

"We'll work with the medical examiner in terms of an official cause of death. Right now there is nothing suspicious about the death," said NYPD Commissioner Dermot Shea.
