Well sounds like more Chinese whispers.

Officials say no explosives have been found at a soccer stadium in Hannover, Germany, despite a report from a German newspaper that a truck bomb disguised as an ambulance was located at the arena.

Lower-Saxony Interior Minister Boris Pistorius, said no explosives have been found at the stadium, HDI Arena. Pistorius, speaking at a press conference, also said no arrests have been made. The stadium was evacuated before Germany’s game against the Netherlands after several credible tips about a possible bombing were reported to German authorities just days after the Paris attacks were carried out by ISIS terrorists.

The newspaper Kreiszeitung reported a truck disguised as a rescue vehicle was found which led to the evacuation of the HD Arena and the cancellation of the game.
And watching the news, a Spirit Airlines plane was evacuated because some bird saw the bloke next to her watching the news on his phone and decided to shit a brick.

Honestly, if their aim is to frighten people, it's working innit?
