In November the Swedish military released images of tracks on the sea bed and an apparent submarine periscope which it said proved that “a mini submarine violated Swedish territory” between October 17 and October 24 and that “at least one vessel” was involved. However, despite widespread speculation that the submarine was Russian, the military never identified its nationality. On Sunday, Swedish daily Dagens Nyheter revealed that a member of the public also photographed what appeared to be a submarine tower on October 31 about two miles (3 kilometres) from the city centre, close to busy ferry traffic lanes.
