A knifeman slashed a police officer's neck before his colleagues finally wrestled him to the ground during a chaotic arrest.
Glynn Leedell, 46, charged at an officer responding to reports of threatening behaviour at Kimberworth Park in Rotherham on July 17.
He inflicted a nasty wound to the back of the policeman's neck which ended up requiring hospital treatment.
The thug was jailed for four years and six months at Sheffield Crown Court on August 29 after previously pleading guilty to wounding with intent.
Now horrific footage has emerged of the attack which took place after officers headed to Leedell's property when multiple people reported him for his behaviour towards a woman.
