The man was detained in the Beersbridge Road area of the city on suspicion of riot on Wednesday morning.
A PSNI spokeswoman said: "He is currently helping police with their inquiries."
Trouble broke out as an Orange Order parade marched past the Short Strand to mark the Twelfth.
According to police, the parade was attacked with missiles from the nationalist area, while more missiles were also thrown into that area.
Seventy-one police officers - 68 PSNI and three mutual aid - have been injured in parades or protest-related violence since 12 July.
