From March, Japan’s internet watchdog will be able to request the removal of instructional posts related to murder, guns and explosives, police said Thursday.

The move comes in the wake of the assassination of Prime Minister Shinzo Abe, whose suspected killer is believed to have built the murder weapon based on information found online.

The National Police Agency said by adding to the types of content that can be requested for removal by internet service providers, it aims to prevent crimes.
