Officer 'punch' caught on camera

A video that appears to show a Met Police officer punching a person is being reviewed by the police watchdog.

Footage shared on social media shows a male police officer striking out during an arrest in north London.

Police said three officers suffered injuries and four males, all aged 16, were arrested.

One of the males was originally detained for the purpose of a search, the Met said. A crowd formed and officers made a circle around the person being searched.
