Danish-Palestinian bad-boy poet Yahya Hassan, who stormed on to Denmark's literary scene in 2013 and quickly became a household name, has died aged just 24, his publisher said Thursday.

The exact cause of his death on Wednesday has not been made public but police said they did not believe it was a criminal act.

"Twenty-four years. That's nothing, this is a catastrophe," Simon Pasternak, head of publisher Gyldendal, said in an Instagram post.
