A woman in her twenties swung a hammer at a university in Japan on the 10th, injuring eight people, local media reported.

According to reports from Kyodo News and NHK, a woman identified as A, a student at Hosei University's Faculty of Sociology, swung a hammer at students during class in a classroom at the Tama campus in Machida, Tokyo, that afternoon.

Eight students in their twenties (five men and three women) sustained bruises on their heads, foreheads, and arms. Five of them were taken to the hospital, while the remaining three, who had bleeding from their heads, received emergency treatment at the school's clinic.

It is reported that about 100 students were in class at the time. The woman A, who was arrested at the school, reportedly stated, "I was ignored by my group and felt pent-up frustration, so I struck with the hammer that was at the university."

A told the police she was a Korean residing in Hachioji, Tokyo.

A Ministry of Foreign Affairs official noted, "The local embassy has been providing necessary consular assistance since shortly after becoming aware of the arrest of our citizen," adding, "Specific details are difficult to mention as this is a matter currently under investigation."
