KYOTO (Kyodo) Police handed a 19-year-old preparatory school student over to prosecutors Saturday for allegedly "disrupting" a university entrance exam last week by using a cell phone to solicit answers online during the test.

The Sendai prep school student, whose name is being withheld because he is a minor, is suspected of cheating by posting questions from Kyoto University's entrance exam on an online help site and using the answers that were provided.

According to the Kyoto Prefectural Police, the student said he entered text from the exam questions into his mobile phone with his left hand during the math and English tests for Kyoto University on Feb. 25 and 26.

The police believe he then wrote down the responses posted by other Internet users on Yahoo Japan's Chiebukuro (Pearls of Wisdom) question-and-answer service with his right hand, they said.

The student also admitted cheating in a similar way on the exams for Waseda, Doshisha and Rikkyo universities earlier the same month, they said.
