The Wire star Robert F Chew had passed away, aged 52.
The actor, who played drug kingpin Proposition Joe in the HBO series, was found in his apartment on Thursday (January 17).
His sister Clarice told the Baltimore Sun that Chew died in his sleep of apparent heart failure at his Baltimore home.
Chew appeared in all five seasons of David Simon's acclaimed drama series, and also had parts in Simon's other HBO shows Homicide: Life on the Street and The Corner.
Jamie Hector, who played Marlo Stanfield on The Wire, remembered his former co-star on Twitter, writing: "I didn't want to believe this #RIP Robert F Chew, Prop Joe will always be remembered Robert Chew will always be loved and missed!"
Michael K Williams, who played Omar on The Wire, also tweeted about Chew's passing: "R.I.P. to the talented Mr Robert Chew #propjoe."
