According to the authorities in Germany, an unidentified flying object was spotted flying over the city at a height of 300 meters on Tuesday.
A member of the public filmed a UFO flying over the Werder Bremen's Weserstadion, in addition to other parts of the city, which provoked local authorities to investigate what was hovering in the night skies.
The sighting of the UFO caused airspace to be shut down for three hours in the city during which time the UFO was said to appear and disappear off radars at the local airport.
A spokesman for the police later said "we do not know what it was but there was something".
