A hairdresser who broke a schoolgirl’ jaw with two kicks was locked up for ten months.
Ruby Radford inflicted the injury when she saw the 14-year-old in Heanor town centre on August 15, a court heard.
Radford claimed the victim had bullied her sister. The victim needed to have two titanium plates inserted in the jaw, which was broken in two places.
Recorder Robin Rowland told Radford: “This was a mean, violent and serious assault.
“Kicking anyone who is defenceless has very serious connotations with the injuries and the view the court will take.
“She had a double fracture of the jaw, requiring an operation and could not eat for three days,” he added at Derby Crown Court.
Radford, 20, of Heath Road, Ripley admitted causing grievous bodily harm. She was sent to a young offenders’ institution.
Will Bennett, mitigating, said Radford was wearing Ugg boots which he described as “slipper-like and soft.”
He said: “It is clear this defendant believed her younger sister was being bullied by the victim.
“This was not a premeditated assault as much as this defendant didn’t seek her out. They happened across each other by chance.
“There is a very brief conversation and unfortunately the victim laughs. The defendant foolishly lost her temper.
“She recognises this must have been a horrifying and extremely unpleasant incident for the victim and she regrets that,” added Mr Bennett.
Alex Wolfson, prosecuting, said the incident took place in the evening and was “an unprovoked attack.”
Sarcastic comments were made and Radford grabbed the girl.
The pair struggled with each other before the girl fell down.
Radford knelt over her and punched the girl, asking: “Do you know my sister?”
When the girl replied “yes,” she was ordered to say it more loudly.
Mr Bennett said: “She lost her temper because of the background. The red mist descended and this extremely unpleasant incident took place. Looking back, the defendant is sickened by her actions. She walked away hoping it would make the situation with her sister better. It has made it worse.
“Her recollection is not perfect because she became so angry.
“She has got a full-time job doing hairdressing, working full time and bringing in an income. She is a trusted employee and people like her.
“She opened up with the probation service and says she has problems with her temper.
“She is in the position to pay compensation and is offering £100 monthly as compensation.”
