Investigations into 57 potential offences at bonfires over the Twelfth are ongoing, the PSNI confirmed.
There was widespread condemnation over the burning of effigies of political leaders, flags and election posters on a number of bonfires over the July 12 period.
Last month, the grand secretary of the Orange Order Rev Mervyn Gibson said the burning of posters and effigies of people on Eleventh night bonfires should be treated as a hate crime.
