The Police Service of Northern Ireland have condemned sporadic disorder which occurred in areas of Belfast, Newtownards and Derry last night.
Assistant Chief Constable Alan Todd said: “The general levels of calls for assistance last night were similar to what we have seen in recent years however we did deal with disorder and disruption which seen 13 vehicles burnt out in Belfast and Newtownards and petrol bombs thrown at my officers in Derry/Londonderry. There were also a number of security alerts.
“No part of this is acceptable and today we are looking at the evidential picture to pursue lines of enquiry.
“I would like to pay tribute to the job that my officers, along with other emergency services, did last night.
“The disorder we have seen has been caused by a small minority of people who have no regard for their communities. No one wants to see disruption and disorder and the people behind these incidents need to ask themselves just what they are achieving.
“I sincerely hope that today passes off peacefully and that the thousands of people who are attending community events and parades can do so enjoyably and safely.
“I would ask all of those with influence to work with us to ensure the safety of all.
“Our priority remains, keeping people safe and I want to reassure people this morning that our response, should there be an further disorder, will continue to be proportionate with the necessary resources in place to detect and deter those responsible."
