Five men have been remanded on bail in Belfast on charges connected to street violence on St Patrick's Day.
The arrests were made after police came under attack during disorder in the 'Holy Land' student area of the city.
The PSNI arrested a total of 19 people following disturbances yesterday.
At Belfast magistrates court this morning, Alan McCrory a 21-year-old student from Charlestown Road in Craigavon, faced two charges of assaulting a police constable and riotous behaviour.
Augustine McAleer, 19, and Enda Ward, 26, both from Loughmacrory Park in Omagh, were each accused of assault and another public order offence.
20 year-old Gary Keenan from Carrickbawn Road in Rostrevor, and Darren Connolly, an electrician from Tievenamara Road in Keady, were both accused of riotous behaviour.
All five were released on their own bail of £500 to appear again in court next month.
It is understood the clashes began after house parties spilled out onto the street.
There were also a number of incidents in Dublin following the St Patrick's Day festivities, including some minor attacks on fire brigades.
Dublin Fire Brigade says 22 car fires and 18 other fires associated with anti-social behaviour were among the calls answered between 6pm yesterday and 3am this morning.
