Tokyo, Japan:
Eight people were injured in a hammer attack at a Tokyo university on Friday, with a 22-year-old student arrested on the spot, Japanese media said.
All of the injured were conscious, according to public broadcaster NHK, which quoted police sources as saying the afternoon attack took place at Hosei University's Tama Campus.
NHK and other media said the attacker, a female sociology student, had brandished a hammer during a lesson.
Several reports said people were bleeding from the head and that the woman had said she had pent-up frustration at being ignored.
Police could not immediately confirm details to AFP about a rare case of violent crime in Japan, which has strict gun laws.
Live footage broadcast by NHK showed a line of emergency vehicles with flashing lights on the campus in the Machida suburb of the Japanese capital.
There have been occasional stabbings and even shootings in Japan, including the 2022 assassination of former Prime Minister Shinzo Abe.
Hosei University was founded in 1880 as a law school and has fifteen faculties, according to its website.
In December, a high school student was stabbed to death and another was injured at a McDonald's restaurant in southwestern Japan. A man was later arrested following the attack.
The teenagers were queuing to order around 8.30pm when the attacker allegedly entered the restaurant in Kitakyushu town and stabbed them both.
In January 2022, three people were stabbed outside the prestigious University of Tokyo, ahead of the nationwide university entrance exams.
The victims included an 18-year-old boy, a 17-year-old girl and a 72-year-old man, police said at the time.
Police arrested a 17-year-old, who was held at the university gate after the early morning attack.
He did not take exams and did not know the three victims, but told police that he “wanted to die after causing an incident because I was not doing well in my studies,” NHK reported.
The two teenagers did not suffer life-threatening injuries, but the 72-year-old was seriously injured, according to local media.
NHK said the university, where 3,700 students were due to take the tests, went ahead with the exams as planned.
