He said: "There is no excuse for excessive force by police or any action that denies people the right to protest peacefully. Ours is a nation of laws for the people who live under them and the people who live under them."

He added: "We have all seen images of protesters and law enforcement in the streets. It is clear that the majority are peacefully protesting. It is also clear that a minority are not."

While he accepted that the shooting had raised passions across much of the community he said: "Giving into that anger by looting or carrying guns or even attacking the police, only serves to raise tensions and stir chaos. It undermines rather than advancing justice."
