In an official statement, the Ontario Science Centre, in Toronto, Canada, claimed to have been sent the footage by a member of the public for analysis.
The statement said: “The Science Centre is reviewing the footage frame-by-frame to determine whether the claim is legitimate.
“With closer examination, we hope to establish whether or not a genuine unicorn sighting has occurred.
“In the meantime, the Science Centre is asking the public to use caution if they think they see a unicorn – do not make any sudden movements or attempt to use flash photography.
“Although legends of unicorns state they are peaceful creatures, scientists worry they may harm themselves or others if they end up on a road or highway.”
The centre set up an emergency unicorn hotline for the public for further information on unicorns or to report any unusual or questionable sightings.
