Actor Keo Woolford, best known for appearing in the Hawaii Five-0 remake as Detective James Chang, has died at the age of 49.
On stage, Woolford played the King of Siam in The King And I opposite Elaine Paige in London's West End in 2001-02.
He also wrote, directed and produced the award-winning 2013 independent film The Haumana.
In 2013, Woolford received a special jury prize at the Los Angeles Asian Pacific Film Festival for best first feature for The Haumana.
He had just completed the script for a sequel and auditions were set to begin in January, publicist Tracy Larrua said.
He also had small roles in films including Falling for Grace, the 2014 remake of Godzilla and Happy, Texas.
But he was best known for playing Detective James Chang in the remake of Hawaii Five-0, which began in 2010.
Woolford's co-stars from the police drama led tributes on Twitter.
Keo's Hawaii Five-0 co-star Daniel Dae Kim tweeted: "As talented as you were, I will remember you most for your kindness. Thank you for sharing your light with us, @KeoWoolford. Rest In Peace."
Woolford last tweeted on November 24, urging the world to stand with the protestors at Standing Rock, who are fighting against the construction of a new pipeline.
He also celebrated voting in the presidential election earlier in the month, tweeting: "Polling place was packed! No matter what happens I believe something good is going to come from all this... #IVOTED."
Brian Yang then tweeted: "So saddened to learn of @KeoWoolford's passing. From NYC to Hawaii, we miss you."
While Lynn Chen shared a photo of the actor at work, writing: "Shocked to hear about the passing of @KeoWoolford, a talented artist and director who will be missed dearly."
Perez Hilton also expressed his sadness at the news, tweeting: "So young!! R.I.P. Keo Woolford."
