I have written about this case on a number of occasions most notably in my autobiography Monster Hunter (2004) and in an article for the newsletter of the Ecology Department of Hong Kong University
The blackened skin of the last tiger shot in Hong Kong is displayed at the Tin Hau Temple in Stanley on Hong Kong Island. The tiger was bagged outside the local police station in 1942 by officer Ruh Singh. The beast weighed in at 240 pounds and was 73 inches long, standing 3 feet tall.
Hong Kong was under Japanese occupation at the time.
