Detective Superintendent Julie Mullan, from the Police Service of Northern Ireland's Professional Standards Department, said: “We have received the report from the Ombudsman and acknowledge its findings.
​
“The Police Service of Northern Ireland and the public expect police officers to investigate incidents fully, fairly and professionally. Where it is perceived that conduct falls short of these high standards, it is right that officers should face an impartial, thorough enquiry by the Police Ombudsman’s office.

“As a result of the investigation, three police officers have been issued with advice  to improve their conduct, while a fourth officer was subject to measures designed to improve performance.

“While in this instance the conduct of the officers fell short of the standards that we have set, it is not representative of the excellent work police officers carry out across Northern Ireland on a daily basis as we strive to keep people safe.”
