Story highlights The man posted a video of it to a Facebook group

The obscure Danish law has only been used 4 times before

(CNN) A Danish man who burned the Quran has been charged with blasphemy, the first such charge in the country in almost half a century.

The 42 year-old man burned the Muslim holy book in his backyard in December 2015 and then posted a video of it to a Facebook group, said Jan Reckendorff, the chief prosecutor
