Japan’s government says it wants to clamp down on websites where vulnerable people can share suicidal thoughts.

The move comes in response to an alleged serial murder case in which such sites were used.

In October, nine dismembered bodies were discovered in coolers and tool boxes in a so-called “house of horrors” in the suburbs of Tokyo.

Investigators found nine heads along with a large number of arm and leg bones.

Takahiro Shiraishi, 27, has admitted to killing nine people since late August in a case that has stunned Japan.
