Scotland Yard is failing to record almost 100,000 crimes each year including violent offences and domestic abuse, a report has found.

While acknowledging that the country's biggest force had made improvements in many areas, a watchdog said around 10 percent of all crimes were still not being recorded properly by officers.

Inspectors said problems had been identified in the areas of violent crime and domestic abuse, public order, theft and damage against property offences.

In some cases problems arose when call handlers wrongly categorised crimes when they were first reported.

But elsewhere officers were failing to record additional offences that were uncovered during the course of their investigations.

Inspectors also found that some officers had a lack of understanding of common assaults where there was only a threat of violence rather than an actual injury.
