"The Wire" star Lance Reddick, 60, died Friday, his publicist said.
Mia Hansen, the actor's publicist, said Reddick "passed away suddenly" and that it was from "natural causes." She did not provide further details.
"Lance will be greatly missed. Please respect his family’s privacy at this time," Hansen said in a statement.
The Baltimore native was best known for his portrayal of a hometown police lieutenant, Cedric Daniels, in the acclaimed HBO drama "The Wire," which ran from 2002 to 2008. He was also featured in the "John Wick" movie franchise.
His career started with small roles, including parts in the Denzel Washington movie "The Siege" in 1998, and on television's "West Wing" in the late '90s and into the early '00s.
About the same time, HBO's "Oz" showcased Reddick's acting chops as he portrayed a Jamaican drug dealer who turned out to be an undercover police detective who had infiltrated the criminal underworld.
Reddick also had a recurring role on television's "Law & Order: Special Victims Unit."
