The Sun has been accused of running a falsified account of how "A Sun investigator managed to smuggle himself 2,000 miles from Turkey to Paris in just six days without showing his passport". It's article was headlined: "6 DAYS TO TERROR" and claimed "WE REVEAL HOW EUROPE IS STILL WIDE OPEN TO DANGER".
The paper claimed its investigator had moved freely across Europe, without checks, by paying people smugglers and hiding in a train toilet to evade Croatian border police - the suggestion being terrorists could do the same. However, the Croatian Interior Ministry has claimed it did register The Sun's investigator both as he entered and left Croatia. It has even published a scan of his valid passport which he apparently presented, according to website Total Croatia News.
The statement from the Croatian Interior Ministry also appears to contradict claims the investigator took "a series of trains up to Paris, dodging the guards on the way" as it says he exited Croatia at Zagreb airport, where he showed a valid passport.
The Sun has removed the story from its website.
