On the 7th, regarding the bomb threat claiming to detonate explosives at Sungshin Women's University and Gwangju Women's University, police suspect it was committed by the same person.
A police official noted at a regular press briefing on the 14th that "the threat emails regarding the (Sungshin Women's University and Gwangju Women's University) terrorism are similar in content and the timing of the sending is close, so we suspect it is the same person." He added, "The Gwangju Police Agency will trace the Internet Protocol (IP) address to determine whether the sender is domestic or overseas."
According to the police, around 11:30 a.m. on the 7th, a suspicious report was received at 112, stating that explosives had been installed at the Lifelong Education Center of Gwangju Women's University located in Gwangsan District, Gwangju.

The author wrote in the email, "I have installed 10 kg of dynamite at one university" and "It will explode at 3:34 p.m., killing many women. Women do not need academia." The email was received around 11:42 p.m. on the 4th. It is known that the email was received by Sungshin Women's University about 10 minutes after it was received by Gwangju Women's University.
