The investigation into a pitch invasion that followed Manchester City's Premier League-winning match is "very much ongoing", police have said.
City fans poured on to the pitch at the Etihad stadium after the club beat Aston Villa 3-2 on 22 May.
Greater Manchester Police said it was investigating a number of offences, including criminal damage.
Releasing images of 23 suspects, the force said a number of fans had "put spectators' safety at risk".
Det Sgt Nicholas Fernandes said the disorder seen after the game "will not be tolerated and we are proactively working with Manchester City to identify the relevant individuals".
