The National Police Agency said Thursday police in Japan have arrested six people on suspicion of Internet fraud since a new law that bans unlawful access to the global online network came into force six months ago.

In a report presented to a meeting of the National Public Safety Commission, the NPA said the arrests were among 35 cases of Internet fraud handled by police across the country in the past six months.

Separately, the agency said it formally asked NTT DoCoMo Inc. on Thursday to fix its popular mobile phone Internet access service to prevent automated prank calls to the nationwide emergency 110 police number.
