A senior police officer has reminded parents of their responsibility to make sure their children do not get involved in rioting after more disorder in the North.
The 100-strong crowd of loyalists that attacked police in Portadown last night was predominantly made up of teenagers, police said.
Three men were arrested during the disturbances in the Corcraine area of the Co Armagh town which was sparked after loyalist flags were allegedly removed at an interface with a nationalist area.
Officers fired 19 baton rounds at the rioters during the violence.
The disorder came at the end of a week which saw violence erupt across the North during the height of the Orange Order marching season.
Police Service of Northern Ireland Superintendent Jason Murphy said a peaceful loyalist protest had been hijacked by those intent on trouble.
He said officers had been attacked with petrol bombs, stones, bricks, fireworks and other missiles.
The commander said a number of Land Rovers sustained substantial damage during the disorder but no officers were injured.
“The loyalist violence in Corcraine last night did nothing for the good name of Portadown,” he said, before warning teenagers not to get involved.
“It is important to remember here the implications that this not only has on the community but to those young people involved in the disorder.
“We would remind parents of their responsibility to keep a close eye on their teenage children to ensure that they do not get caught up in this violence and of the long-term implications this could have on them if they are arrested.
“No one wants their child to start their adult life with a criminal record.”
He added: “The peaceful protest that had been assured by the loyalist community took place, but it was clear that there were faceless individuals within the crowd who were intent on violence.”
The officer commended community representatives who had worked to restore order.
“Despite the violence against my officers last night, I can assure the public of Portadown that we remain steadfast in our determination to work with all communities to make Portadown safe,” he added.
“The law abiding people of Portadown want to see peace, harmony and most of all prosperity and we stand ready as a police service to play our part.”
Two men, aged 24 and 42, were charged with riotous behaviour and criminal damage in the wake of the trouble. The 42-year-old was also charged with possession of an offensive weapon in a public place.
A 20-year-old man arrested in the area was charged with disorderly behaviour, resisting police and assault on police but those counts were not linked to last night’s disturbances.
