Usman Nurmagomedov almost got into a fight with hotel security in Abu Dhabi before attacking Merav Devlishvili.
According to Mash Besport, they didn't want to bring the Russian's company into the foyer, since there was a closed RAF event there, which Osman had nothing to do with. So he started yelling, waving his arms and getting pushed around by security. One way or another, they went inside and had a lobby fight in the street.
After the fight and the arrest, Nurmagomedov and his friends refused to come to the police station - he said he would come there in his car. He arrived and is still in police custody. On social media, Sean Strickland called Osman and his brownies bastards. People supported him and started hating his brother Habib, Trullo and calling him names in every possible way.
