Tokyo police have arrested a Chinese national on suspicion of involvement in apparent cheating on a university entrance exam for foreign students this year.
NHK learned that another Chinese who allegedly provides homework assistance was asked to solve questions just before the exam of Hitotsubashi University in Tokyo in January.
After the test began, the person reportedly received via the internet an image of math questions apparently taken during the exam.
Apparently due to suspicion, the person did not act on the request and reported the incident to the university.
Investigative sources said the Tokyo police worked to identify who sent the image and arrested the Chinese national on suspicion of fraudulent obstruction of business on Wednesday.
The examination was held for foreign nationals who hoped to study at the university. Several dozen people were taking the test at the time.
The university said it will cooperate fully with investigators.
In a separate case, the Tokyo police have filed papers with prosecutors against two people, one of whom sat for Japanese standardized university entrance exams in January, on suspicion of cheating during the tests. The examinee admitted to leaking world history questions with a request for answers.
