According to a Russian news website, about 50 Middle-Eastern migrants, who had been expelled to Russia from Norway, began to harass girls at a club in Murmansk. A mob of Russians then beat hell out of them. "They realised too late they are not in the European Union."
Police arrived and apparently did't really disapprove of what was happening. But they took 33 of the "migrants" to hospital and 17 to hospital.
Local law enforcement officially denies this incident took place, but there is lots of talk about it on social media.
