Police have confirmed 15 arrests related to St Patrick's Day celebrations in student heartland - the Holylands - and Belfast city centre.
They said the alleged offences involved a range of public order offences such as disorderly behaviour, resisting arrest and minor assaults including assaults on police.
But commended the much improved behaviour on show this year.
Superintendent Melanie Jones said: "Thankfully there was no repeat of the disgraceful levels of behaviour that we saw in the Holylands last year however, police and partner agencies responded to numerous reports of unacceptable anti-social conduct and young people drinking alcohol in the street. In fact, the majority of those arrested were under the influence of alcohol.
"A significant police and partnership operation was in place to help ensure the celebration passed off in a largely peaceful fashion and, with the exception of a few, most people who attended the city centre parade, or who celebrated independently, did so in a good natured and respectful fashion.
"A clean-up operation will obviously take place today and, in due course, police along with partner agencies, and in consultation with the local community, will review all of the planning for St Patrick’s Day and its associated events and will take away whatever learning there is to improve the experience in future for residents and visitors alike."
