A jilted woman spared jail for repeatedly stabbing her mother was today behind bars for threatening to knife her former boyfriend in the back when he dumped her.

Susan Ayrey, 23, was locked up for 20 months after sending a series of menacing text messages to Anthony Osbourne in which she threatened to stick a weapon in him.

The “sinister” messages were sent only weeks after a judge sentenced her to two years’ imprisonment, suspended for two years, for wounding her mum, Elaine, with intent to do her grievous bodily harm.

Mrs Ayrey, 49, suffered life-threatening injuries to her chest and back when her daughter seized a kitchen knife and stabbed her up to four times.

Mr Osbourne heard the graphic details of what his girlfriend had done for the first time when he attended Bradford Crown Court for the sentencing hearing on November 7 last year.

She was not jailed because Judge John Potter said it was an exceptional case.

Mrs Ayrey had put her daughter into care when she was a child and told her she wished she had never been born in the moments before the stabbing.

Prosecutor Ken Green told the court yesterday Ayrey, of Lindholme Gardens, Allerton, Bradford, and Mr Osbourne, of Darlington, began a relationship when she contacted him on Facebook while she was in a bail hostel awaiting sentence.

The couple had been friends in the past but lost touch for five years.

“He decided to stick with Miss Ayrey, saying she had never shown any aggression towards him,” Mr Green said.

But in December, Mr Osbourne ended the relationship, saying they lived too far apart.

“She was angry and abusive but seemed to calm down when he said they could still be friends,” he said.

On January 19 at 11pm, Mr Osbourne received a text message from Ayrey, whose number he had deleted from his phone.

She said it was “Susie” and when he told her to leave him alone, she replied: “Ha. Guess wot. I am moving Bk to Darlo Wednesday w***** so watch ya Bk.”

When he pretended he had moved away, Ayrey texted in reply: “Yep, so watch ur BK B4 I stamp all ova ur head t*****.”

Mr Osbourne, by now seriously alarmed, threatened to tell the police, to which Ayrey responded: “Ha. Don’t think so, watch ur BK B4 u get something stuck in it like a knife and u no I will do it. I have done it before. Not so cleaver (Sic) now R Ya.”

Mr Green said Mr Osbourne was very frightened.

“He lived alone. He knew what she was capable of and he felt he had to be constantly looking over his shoulder for fear of what might happen to him.”

Ayrey pleaded guilty to harassment of Mr Osbourne and a Bail Act offence for failing to attend an earlier court hearing.

Her barrister, Sheila Whitehead, said she was deeply sorry for the trauma she had caused Mr Osbourne.

She was vulnerable and supported in the community by the probation service supervision that formed part of the suspended sentence.

Judge Potter said Mr Osbourne was scared and frightened by the “sinister” text message that made specific reference to the stabbing of Ayrey’s mother.

“Effectively, you used that previous offending as a threat to another person close to you,” he said.

He revoked the suspended sentence order and jailed Ayrey for 19 months, with a month consecutive for the harassment offence.

Judge Potter made a restraining order without limit of time banning Ayrey from contacting Mr Osbourne.
