LOS ANGELES – James MacArthur, who played Detective Danno Williams on the original TV hit Hawaii 5-0, has died aged 72, according to the Hollywood Reporter Thursday.
The catchphrase "Book-em Danno", uttered by Steve McGarrett who was played by the late Jack Lord, is considered one of the most popular lines in US television history.
According to MacArthur's agent, Richard Lewis, he died of "natural causes" in Florida.
Apart from his landmark role in Hawaii Five-O, MacArthur starred in films such as Battle of the Bulge and Swiss Family Robinson.
Besides acting, MacArthur was a world traveller. He once spent six months driving his Land Rover from London to Malawi in southeast Africa.
He left behind his wife H.B Duntz, four children and seven grandchildren
