A night of trouble ensued as Eleventh Night bonfires were lit across Belfast and further afield.
While there were no major reports of disruption in Co Armagh, however, Belfast did not get off so lightly.
Police attended a number of security alerts throughout the day and into the night, with Belfast’s City Airport put into lockdown at one stage.
It came after a suspicious object was discovered on the Sydenham Bypass.
Despite being declared a hoax, passengers were forced to stay inside while the object was examined.

It came after police had discovered the remnants of what is believed to be a viable pipe bomb type in Clandeboye Drive area of east Belfast.
A similar device was also discovered in Ravenhill Avenue.
A bus in Newtownards was hijacked around 7.30pm by a group of men, with one believed to have brandished a firearm.

Strangford MLA Kellie Armstrong said: “The Eleventh night is supposed to be a night to celebrate culture, not to destroy local infrastructure. The wanton actions of a minority determined to ruin our Community will mean money that should be spent to improve the area will now have to be spent fixing a burned road and to replace a torched bus.
“It may also mean delays and diversions for many people who are taking part or spectating tomorrow’s 12th parade in Newtownards.
“There is no need for this type of destruction. It’s time those who are behind this destruction to stop and consider the damage they are doing to the whole Community through their disgraceful actions.”
Assistant Chief Constable Alan Todd appealed to those who have influence in this community to discourage people from taking part in any illegal activity.
