It will be interesting to see how eager this guy is going to be to go back to North Korea anytime soon:
A 29-year-old Australian student detained in North Korea surfaced in Beijing airport on Thursday, saying he was in “very good” spirits after being released.
Alek Sigley ― one of a handful of Westerners living and studying in North Korea ― disappeared without a trace around June 23, prompting a week of deep concern and frantic speculation about his fate.
For days Sigley’s family received no word about his whereabouts or wellbeing, stoking fears he may be the latest in a long line of foreigners to become entangled in North Korea’s police state.
Then, with little warning, Australian Prime Minister Scott Morrison on Thursday told lawmakers that Sigley had “been released from detention in the Democratic People’s Republic of Korea” and that “he is safe and well”.

You can read more at the link, but there has been speculation that his detention may have been linked to the Trump-Kim summit at the DMZ. The North Koreans may not have wanted word of the meeting to leak and took extreme precautions to include detaining this Australian man until after the summit was complete.
