CC Learmouth said:
"The disorder that occurred in parts of England last August was unprecedented. The service has learned a number of lessons from that period. We are always striving to improve the policing service to the public, and how we police public order is no exception.
"There have been significant improvements already in terms of intelligence systems, tactics, training and deployment that strengthen our ability as a service to respond to large scale incidents of disorder and ensure we do our very best to protect life and property.
"I am enormously grateful for the overwhelming support the police service received from the public during that period of great difficulty, and for the selfless hard work of all the officers involved in policing the disorder as well as those involved in the subsequent investigation and prosecution of offenders."
