The consequences of police officers not properly recording crimes are "serious", the head of the police watchdog has said.
The Chief Inspector of Constabulary, Tom Winsor, was speaking after a report claimed officers may be failing to record as many as a fifth of crimes.
The consequences of under-recording of crime are serious, and may mean victims and the community are failed because crimes are not investigated, the levels of crime will be wrongly under-stated, and police chiefs will lack the information they need to make sound decisions on the deployment of their resources.
