Police have made 100 arrests since rioting erupted in Ballymena, Co Antrim earlier this year and spread to other areas of Northern Ireland.
A senior PSNI officer said that an investigation into the violence was continuing and this was providing "reassurance to local communities" that were impacted.
Violence erupted in Ballymena in June after an alleged sexual assault of a girl in the town.
Two 14-year-old boys were charged with attempted rape.
A peaceful protest in Ballymena over the alleged assault was followed by attacks on police and properties housing ethnic minorities, described by the PSNI as "racist thuggery".
The disturbances lasted for several nights and spread to Portadown, Larne, Belfast, Carrickfergus, Derry and Coleraine.
The PSNI said that its investigation has resulted in 100 arrests with 91 people being charged with offences including riot, arson with intent to endanger life and burglary with intent to cause arson.
The force added that cases are being prosecuted in court.
Throughout the course of the team's investigation, photographs of 60 potential suspects were issued, leading to 49 arrests.
Detective Chief Inspector Michael O’Loan said: "On June 9th hate motivated, serious public disorder unfolded in Ballymena which saw the homes of ethnic minority families destroyed and violent crowds attack police officers.
"Consecutive nights of sustained disorder in Ballymena and other parts of Northern Ireland followed until calm was restored.
"A dedicated investigation team was established to carry out a focused investigation into what happened and we brought together specialist resources to ensure a thorough and swift review was conducted."
DCI O'Loan said the investigation team had worked through over 1,000 hours of camera footage, as well as a large volume of online material.
"This team’s work has been vital in restoring calm and providing reassurance to local communities in Ballymena and across Northern Ireland by identifying, and holding those responsible accountable for their actions.
"A number of suspects remain unidentified and their images have been published on our website and social media platforms.
"I would appeal to these individuals to come forward and hand themselves into the police or if you know who they are please tell us."
DCI O'Loan said: "The police service remains committed to maintaining public order, and we would strongly encourage anyone with information about what happened or who was involved to make contact with us.
"The Police Service of Northern Ireland will do everything we can to prevent hate crime and bring those responsible to justice.
"We do not underestimate the impact hate crimes have on victims, their families and wider communities.
"It is totally unacceptable that anyone is targeted because of their race.
"No one should feel intimated or threatened due to their ethnicity and officers will continue to pursue justice for the victims of hate-related crime."
