Japan will consider fresh measures against stalking involving GPS devices after the nation's top court ruled in July such activity does not violate the existing anti-stalking law, police said Thursday.

The National Police Agency said it will set up a panel of experts on Friday to study revision of the law regulating stalking to better protect victims. The panel is expected to compile a proposal on the issue by the end of January, according to the agency.

The Supreme Court ruling said that, as the current anti-stalking law only bans monitoring victims around certain locations, such as their residences and workplaces, securing location information remotely does not infringe on the legislation.
