An investigation has found that police were justified to use a baton and a Taser to arrest an armed man.

Officers responding to an incident in Troon, found an 'intoxicated' man who was armed with a large knife.

They reported him to be behaving in an unpredictable and erratic manner and threatening to harm himself with the knife.

Armed police officers were sent to the incident to assist their unarmed colleagues.

Over half an hour, officers attempted to negotiate with the man to surrender the knife, but he refused, according to the Police Investigations and Review Commissioner report.

He then became more erratic, waving a knife at officers and threatening to stab himself in the throat.

An firearms officer then discharged a baton round to stop the man, but he continued his behaviour.

Another firearms officer then discharged a Taser at the man who was then incapacitated, allowing officers to control and arrest him, removing the threat to himself, the officers and the wider public.
