(CNN) -- A BBC journalist who got into North Korea by using a group of students from a top British university as camouflage is facing accusations that he recklessly endangered their safety and damaged the school's reputation. BBC reporter John Sweeney posed as a student from the London School of Economics and Political Science, or LSE, on a visit to the secretive nation last month, during which he filmed footage for the broadcaster's prime-time current affairs show "Panorama." He traveled with his wife and a cameraman. Officials and student representatives from the LSE say Sweeney didn't fully explain the situation to the students he was traveling with in advance, saying only that "a journalist" would join the trip. In doing so, they say, he put the students at risk and jeopardized future visits by the school's academics to North Korea and other politically sensitive countries.
