A thug daubed racist graffiti on the home of an African woman before attacking her in the street and knocking her unconscious, a court heard.
Adam Moran, 22, was jailed for 23 months for the attack on his 41-year old victim after she went to look at the abuse – including a death threat – he'd sprayed on her garage door and wheelie bin.

Alisha Kaye, prosecuting, told Leeds Crown Court the victim had reported problems with youths in the period leading up to the incident in Pontefract on August 8.
Moran wrote messages on her property which read "Tell us to get off again and I will kill you" as well as racist insults before signing his nickname 'Jackass'.
The woman, originally from Zambia, came out of her home.
As she went to take photographs of the damage Moran then hurled vile insults at her including: "You are my slave. You used to shine my shoes. Why don't you go back to your own country?!"
He then grabbed her by the hair before punching, kicking and kneeing her while constantly shouting abuse, the court was told.
A neighbour saw what was happening and ran over to try to help but Moran then swung a punch at her.
His first victim spent two days in hospital with head, back and leg injuries.
Moran later told police his nickname was Jackass but denied the damage.
He claimed he attacked the woman after she dug her nails into him when he went to confront her.
Moran, of Thomas Hill House, Horsefair, Pontefract, pleaded guilty to racially aggravated assault occasioning actual bodily harm, common assault and two offences of racially aggravated damage.
He has previous convictions including burglary, robbery and assaulting a police officer.
Richard Canning, mitigating, said: "He acknowledges that his behaviour was quite frankly appalling and he is very ashamed of it."
Jailing him, Recorder David Hatton said: "These were serious offences, fully motivated by your approach to this woman's background and race."
