Four police officers were injured during the disorder and received medical treatment. Supt John Menzies said: "I would like to thank our partner agencies and the wider public for their support.
"Unfortunately, we experienced some disorder including the use of pyrotechnics and alcohol-related offences. We took robust action to prevent these escalating. "Violence and assaults on members of the public or police officers is completely unacceptable and we continue to work to identify those responsible."
