A woman's arm was broken while being arrested last year, due to a Police officer using a poor restraint technique

That's according to an Independent Police Conduct Authority report which looked into Police arresting a number of people in central Hamilton on July 9, due to a disturbance at a property.

While arresting a woman, an officer changed his grip while restraining her, resulting in her arm being broken.

The Authority has found it wasn't caused by excessive force, but by a poor restraint technique.

Hamilton Police have reviewed its practice in relation to the use of restraint holds.
