Officers attacked at St Patrick's parade in Kilrea

Eight people were arrested for offences which included assault, disorderly behaviour, drugs offences, motoring offences and on warrant during the celebrations in Portstewart.

A considerable quantity of alcohol was seized in the resort, and police say that they were concerned at the number of people who engaged in on-street drinking.

Police say they are reviewing the policing operation that took place in Kilrea, following disturbances after the St Patrick’s Day parade in the town.

In a statement, the PSNI said: “We are aware of the concerns raised by the community following a number of incidents of public disorder on St. Patrick’s Day in Kilrea.

“Officers responding to reports of the disturbances came under attack themselves as they sought to restore order.

“At one stage bottles were even thrown at an ambulance which had been called to the village.

“We are currently reviewing the policing operation to satisfy ourselves that our response was both appropriate and proportionate, and we will be seeking to meet and discuss the matter with local representatives as soon as possible.”

On St Patrick’s night a loyalist band parade took place in Coleraine, and police have praised the organisers of the event, which passed off peacefully.

Chief Inspector Nicky Thompson said: “I want to praise the organisers of Wednesday night’s parade for the way it was controlled and conducted. The event was well marshalled, started promptly, and also finished ahead of schedule.”
