This is the reason Trump is coming to his defense.

It looks like the the two guys were stalking A$AP Rocky and his security and at the beginning of the encounter, one attacks his security guard and throws his headphones at him, which are then broken. According to the security guard they cut his head.

The security guard, showing restraint, just keeps telling the guy to go away, as does Rocky, saying they don’t want to fight. But the two guys, who appear to be Afghani refugees, just wouldn’t let them go and keep following them. Eventually the encounter led to a fight with Rocky throwing one of the men to the ground. He has now been held for almost a month in jail, at least part of that time in solitary. There is no right to bail in Sweden which is crazy.
