I think I actually had an encounter with this guy, in Logan Circle on P Street in December. I was walking minding my own business and he came up next to me with a horrible gash on his hand asking me if he should go to a hospital. I didn't realize the situation at first and made the mistake of telling him yes, he should go to a hospital, or he's at risk of losing the hand. He took my response as an invitation to follow me around asking for $8, eventually getting a bit more aggressive then giving up. His eyes and his demeanor indicated he had been using drugs. I saw him again about a month ago, pestering people around 14th and K.

Not 100% it's the same guy, but the appearance and behavior are exactly the same. The sudden bursts of aggression are very concerning and people should be careful

EDIT: I just saw your other comment about him calling you a homophobic slur for not giving him money. He did the same to me for some reason, I really think it's the same guy
