Being able keep calm under pressure is always a bonus but none of us expect to trigger a man hunt before taking an exam!

Shortly after 8.30am, police began a search for a man who was reported as behaving suspiciously during the morning commute. The man was allegedly reading a book on terror and acting strangely. He then made a hasty exit from the train at Denmark’s busiest transport hub.

Police quickly responded to a tip-off from a fellow train passenger and descended upon Nørreport. A subsequent search for the man extended throughout the city, including police sweeps of Copenhagen Airport and Christiansborg.

But at an afternoon press briefing, police announced that they had identified and contacted the man and that he was “completely clean”.

During their search, police released several photos of the man and asked for the public’s help in identifying him. According to police, it was a tip-off from the man’s family that led to his identification.

“It was apparently someone who had been very nervous because he had to take an exam,” Lauridsen said.

21-year-old University of Copenhagen student Alisiv Ceran was interviewed by TV2 News.

"I was going to an exam and I sat in the train reading a book on 9/11 and I was very nervous. I noticed that a woman was looking at me, so I tried to smile to her. But then I ended up knocking my bag over and then my printer fell out with a whole bunch of cables," 

Ceran said he studies English at the University of Copenhagen and that his exam was on the war against terror as part of a course in American foreign policy.
