Big Balls was in an area that has a known drug trafficking problem and was attacked by 2-12 people(we don't know how many actually there were). They've arrested 2, a 3rd has been identified as a person of interest and that's it, 3 of them.
The police have now admitted the cop who arrived on the scene and scared away the attackers was there because it's a known area for drug sales and under the new Trump EO they are now regularly patrolling it and the patrol officer car happened upon the attack. So Big balls went to a known area to buy drugs, got pummeled and now Trump is federally controlling DC as a result
