Overview

• Police evacuated about 500 students from a high school in Busan’s Dong District after a faxed threat received around 12:30 a.m.; a special unit is searching the campus and the fax is believed to have originated from Japan.
• On Thursday in Seoul, six high schools received faxed threats under the name “Takahiro Karasawa,” with a seventh school later getting a phone threat, prompting evacuations and some early dismissals but no explosives found.
• Seoul authorities classified the latest faxes as low risk due to prank‑like language, increased patrols near schools, and shared response guidance without deploying special units.
• Officials report 55 similar threats since August 2023, including 14 this month, and say the pattern likely points to a single perpetrator under consolidated investigation.
• Investigators are working with Japanese and other partners to trace messages sent via relay services and VPNs, and a separate case led to the Aug. 5 arrest of a Jeju middle schooler over a false online bomb claim at a department store.
