North Korea has detained a U.S. citizen, officials said Sunday, bringing to three the number of Americans now being held there. Tony Kim, who also goes by his Korean name Kim Sang-duk, was detained on Saturday, according to Park Chan-mo, the chancellor of the Pyongyang University of Science and Technology. 
Park said Kim, who is 58, taught accounting at the university for about a month. He said Kim was detained by officials as he was trying to leave the country from Pyongyang's international airport. A university spokesman said he was trying to leave with his wife on a flight to China.
The Swedish Embassy in Pyongyang said it was aware of a Korean-American citizen being detained recently, but could not comment further.The embassy looks after consular affairs for the United States in North Korea because the two countries do not have diplomatic relations. 
The State Department said it was aware of the report about a U.S. citizen being detained, but declined further comment "due to privacy considerations." Park said Kim had taught at the Yanbian University of Science and Technology in China before coming to Pyongyang. He said he was informed that the detention had "nothing to do" with Kim's work at the university but did not know further details.
The Pyongyang University of Science and Technology is the only privately funded university in North Korea.
