A TEENAGE girl who carried out a knife attack on her ex boyfriend has been sentenced to 18 months detention and training.

Danielle Carroll, 17, of Abbot Clough Avenue, Blackburn, lashed out with two weapons, causing arm wounds.

Victim Jamie Gardner was at Preston Crown Court to lend her his support as she was sentenced after pleading guilty to unlawful wounding.

But imposing the detention term, the judge, Recorder Christopher Melton QC, said "Stabbing or slashing people with knives is very dangerous. People die from being stabbed or slashed with knives, even if the people who do it didn't intend it.

"I don't know why you behaved like this".

The court was told she and Mr Gardner had had an on off relationship.

On the evening of August 14 last year, he had been on a night out with friends. He ended up getting out of a vehicle in Hereford Road, Blackburn, intending to visit a cousin.

A scuffle took place between him and the defendant, ending with him walking away.

Miss Rachel Woods, prosecuting, said Mr Gardner went on to realise he must have dropped his mobile phone and returned to the scene.

Carroll was stood with a hand behind her back. She shouted she would stab him and as he got closer, revealed an eight-inch bladed kitchen knife.

She stabbed towards his right bicep. He ended up on the floor, but managed to disarm her.

Miss Woods added: "He felt a pain to the right forearm and saw a small vegetable knife in the defendant's left hand."

He was treated at hospital for a four-inch cut to the upper arm and a one-inch wound to the right forearm that needed three stitches.

The prosecution said Mr Gardner had been reluctant to involve the police.

Twelve days before the offence, Carroll had been given a supervision and curfew order for affray.

Miss Kath Johnson, defending, said Mr Gardner had wanted to retract his statement at an earlier stage. He was at court for the sentencing hearing, wanting to offer his support.

Carroll had never received a custodial sentence before.

Miss Johnson added: "There has been some increasing maturity on the defendant's part and a change in her attitude.

"She recognises she is the author of her own misfortune.

"She had been in a volatile relationship with Mr Gardner.

"The injuries which resulted were not of the most serious type".
