American actor Michael K Williams, best known for starring in HBO drama series The Wire, has been found dead in his New York apartment. He was 54.
US media quote law enforcement sources as saying he died from a suspected drug overdose. This has not been officially confirmed.
Williams – who was nominated for three Emmy Awards – had openly discussed his struggles with drugs over the years.
In The Wire, he played Omar Little, a gay, streetwise robber of drug gangs.
He was also known for playing Albert “Chalky” White, a powerful gangster, in the Prohibition period TV series Boardwalk Empire.
New York Police Department spokesman John Grimpel said police went to Williams’s Brooklyn apartment after receiving an emergency call at 14:00 local time on Monday (18:00 GMT).
Fellow actors and filmmakers have been paying tribute on social media.
