Clarity Kennedy flew into a rage the morning after she celebrated reaching adulthood at a house party on December 3 last year. She accused friend Laura Creedon of drinking her bottle of booze and demanded she pay £80 for it.
When Miss Creedon refused, Kennedy threatened her with an eight-inch kitchen knife, Warwick Crown Court heard yesterday.
After refusing to let Miss Creedon leave the flat in Stratford-upon-Avon, Warwickshire, Kennedy told her she was keeping her “hostage” before taking the empty bottle and battering her over the head with it.
Prosecutor Amrisha Parathalingam said: “After the party, Kennedy, her friend and Miss Creedon remained at the flat, with Miss Creedon sleeping on the sofa.
“But in the morning the defendant began kicking off about some expensive vodka she had brought to the party.
“Kennedy got an eight-inch kitchen knife and began waving it around, threatening Miss Creedon that she would put her in handcuffs and stab her if she tried to call the police.
“She told her: ‘I’m keeping you hostage until you give me the money. If you try to leave, I’ll cut you up.
“If you don’t give me the money, I’ll smash this bottle over your head’.”
Kennedy then smacked her several times over the head with a bottle leaving Miss Creedon with bumps and bruises.

“This particular, very nasty incident began between three hungover individuals arguing over the consumption of a bottle of vodka Miss Kennedy had bought for her birthday.
“She believed the victim was responsible for drinking it, and things got out of hand.
“She says she lacked any knowledge that her action would be classed as false imprisonment. She deeply regrets her behaviour.”
The Sun reports Judge Peter Cooke saying: “There’s no guideline for false imprisonment, but it is not just what is done to them, it’s that their freedom to get away from it is curtailed.”
“What you did to your friend, when the two of you woke up hungover that morning, was appalling.
“If a proper adult had done that, then after a trial they wouldn’t be getting any change out of two years in prison.
“But you were barely an adult.
“This was the day after your 18th birthday, so I think we ought to be in the realms of two-thirds of what an adult would receive.
“So we are looking at a sentence of about 14 months to reflect the wickedness of what you did.”
Kennedy, from Leamington Spa, Warwickshire, admitted false imprisonment and assault and was sentenced to 14 months suspended for two years and ordered to carry out 60 hours of unpaid work.
