An elementary school in the city of Toyama near the site of a shooting and stabbing incident last week said Monday it will remain closed after a threat was made to attack it.

An email warning that an attack would take place Wednesday against Okuda Elementary School in Toyama Prefecture was sent to Asahi Shimbun Co., a major daily newspaper publisher, according to local police.

The police will look into the threat as a case of intimidation or forcible obstruction of business.
