An email threatening and claiming responsibility for the Jeju Air passenger flight disaster that occurred on the 29th at Muan Airport, Jeollanam-do, was sent to the Ministry of Justice, prompting a police investigation.

According to police on the 30th, an employee of the Ministry of Justice reported to 112 at around 8:50 a.m. upon receiving an email claiming responsibility for the Jeju Air incident. The email allegedly included content suggesting high-performance bombs would be set off in various urban centers in Korea on the night of the 31st.

The email was sent under the name 'Takahiro Karasawa,' presumed to be Japanese, and was written in Japanese and English. This name matches the sender of a threatening email last August, which had threatened bomb attacks on various public facilities in the country. At that time, a Japanese lawyer actually named 'Takahiro Karasawa' stated via social media that it seemed someone was using the name without permission.

The Seoul Metropolitan Police Agency's Cyber Investigation Unit is reportedly considering the possibility that the email reported this time might be the act of the same individual and is merging the investigation with existing cases.
