Hurling abuse wasn't the problem for Petra Mills. But a court ruled that calling her New Zealand neighbour an Australian was racist and against the law.

Czech-born Mills, 31, has been found guilty of racially aggravated public disorder after a rant at her New Zealand-born neighbour in Macclesfield, south of Manchester.

Chelsea O'Reilly, who has dual British and New Zealand citizenship, said: "She called me a stupid fat Australian b****. Because of my accent there can be some confusion over my nationality. She knew I was from New Zealand.

"She was trying to be offensive. I was really insulted. She said she would kill my dog. Bizarrely she then blew raspberries at me like a child."

The incident happened when O'Reilly was giving a statement to police about a domestic incident between Mills and Mills' husband in early September, the Daily Mail reported.

Mills, who had called the police after running from her house, had stormed over to O'Reilly's house and began screaming at her.

Two police constables told the court they had heard Mills use the word "Australian" during her drunken rant.

At Macclesfield magistrates' court Mills agreed she had shouted but denied she was being racist.

"I did not use the word 'Australian'. I used to live with an Australian person. She was very nice."

But chairman of the bench Brian Donohue said: "You were in an emotional and inebriated state. The word 'Australian' was used. It was racially aggravated and the main reason it was used was in hostility."

Mills denied the charge of racially aggravated public disorder but was found guilty and fined £110. She admitted assaulting a police constable by kicking him in the shin and knee and was fined £200 on that charge. She was also ordered to pay both victims £50 compensation, and £500 court costs.

Mills and her husband moved to Scotland after the incident.
