A video has been revealed of a Newport Pagnell man repeatedly banging a female police officer's head against the ground.
25 year old Craig Radbourne has been jailed for three years.
He attacked the officer in Basingstoke last summer after she arrested him on suspicion of being drunk and disorderly.
The attack was caught on her body-worn video camera.
