Assistant Chief Constable Anthony McNally said: “Our thoughts today are very much with everyone who has been affected by this awful and tragic incident.

“We recognise that this will again be a particularly difficult day for Shannon McQuillan’s family, Owen McFerran and his family. 

“We also recognise the impact that this incident had and continues to have on our officers and their families.

“We accept that more could and should have been done by police to prevent the circumstances that preceded Shannon’s death and Owen’s injuries. For that we are truly sorry.

“We will now take further time to carefully consider the Ombudsman’s report and assure ourselves that lessons have been learnt particularly around the identification of vulnerability, risk assessment and adherence to service policy.”
