Later, it was reported that Kim Jong-un attended the Liebefeld Steinhölzli state school in Köniz near Bern under the name "Pak-un" or "Un-pak" from 1998 until 2000 as the son of an employee of the North Korean embassy in Bern. Authorities of Köniz confirmed that a student from North Korea, registered as the son of a member of the embassy, attended the school from August 1998 until the autumn of 2000, but were unable to give details about his identity. Pak-un first attended a special class for foreign-language children and later attended the regular classes of the 6th, 7th, 8th, and part of the final 9th year, leaving the school abruptly in the autumn of 2000. He was described as a well-integrated and ambitious student who liked to play basketball. However, his grades and attendance rating are reported to have been poor. The ambassador of North Korea in Switzerland, Ri Chol, had a close relationship with him and acted as a mentor. One of Pak-un's classmates told reporters that he had told him that he was the son of the leader of North Korea. According to some reports, Kim was described by classmates as a shy child who was awkward with girls and indifferent to political issues, but who distinguished himself in sports and had a fascination with the American National Basketball Association and Michael Jordan. One friend claimed that he had been shown pictures of Pak-un with Kobe Bryant and Toni Kukoč.
