The severed head and two legs of a cat were found in a park in Nasukarasuyama City, Tochigi Prefecture, last month, police said Wednesday.
The grisly find was made by a man who was jogging in Ooke Sports Park on Sept 20, Sankei Shimbun reported.
Police also said that 1,100 fish in the park's pond had been found dead on Oct 1. An analysis of the water showed traces of chlorine.
The park said it has installed more surveillance cameras to beef up security.© Japan Today
