Lukasz Urban, a Polish truck driver, is believed to have been the first victim of the Berlin Christmas market attack.
It is now believed that Urban was killed by a suspect who hijacked his truck before that suspect drove into the crowd in Berlin.
Urban was a married father of one.
Urban, who was from Poland, was described as being "dedicated" to his job and one colleague believed he had fought "to the end."
A tweet from Berlin police said they believe the truck might have been stolen: “There is the suspicion that this lorry in Poland by a construction site has been stolen. The investigations to run. #Breitscheidplatz.”
