A mother-of-three armed herself with a brick to attack a woman she believed was sleeping with her boyfriend, a court heard.
Kerry Fisher (31), went to the victim’s home in Mansfield, and struck her as she answered the door.
The victim suffered a cut above her eyebrow which needed six stitches, Nottingham Crown Court heard.
She also had a lump on her forehead.
She denied she knew the man involved.
Fisher, of Sywell Close, Sutton, pleaded guilty to assault causing actual bodily harm.
Her barrister Gurdial Singh said she was of previous impeccable character.
She had been given some information and snapped.
The attack on 20th September was not premeditated and she had expressed her shame in a letter to the court.
The judge, Recorder Andrew Lockhart, said Fisher had been drunk and taken the law into her own hands.
“This was a vicious assault with a brick. You are cashing in every chip you have and I am just persuaded to suspend the sentence.”
The sentence was 12 months suspended for two years, with a three months tagged home curfew from 7pm to 7am and 150 hours work for the community.
