A heartless mum who threw her own hapless baby at a police officer causing him lift-changing injuries has walked free from court.

Brutal baby thrower Kirsty Bearfield, 24, hurled her child at the woman when she was told her kids would be taken from her care to stay with their father.

She had been at Hull Royal Infirmary with her two children, their father, a social worker, and two police officers on November 20, 2017, after a report of a "non-accidental" injury to the older child, reports Hull Live.

The injury was not found to be suspicious, but to allow for the consideration of "further evidence and other considerations", the social worker, or her supervisor, decided the children should be removed for that night.

Kirsty was angry her kids were being taken away from her

Prosecutor Phillip Evans said: "That was news which the defendant did not take well."

Bearfield was seated on a sofa in a waiting area with the baby on her knee, with a detective constable stood in front of her explaining the decision.

Mr Evans said: "Upon hearing this news the defendant, say the Crown, threw (the baby) at the officer with a look of anger on her face."

The officer "put her arms up and caught (the baby) who had been flung towards her".

The officer suffered life-changing injuries thanks to Kirsty's throw

The officer put her head back so the back of the baby's head would not hit her face, and managed to catch the infant without him being injured. He weighed 13kg, or 30lb, the court heard.

The officer was in "immediate discomfort", and after visiting a physiotherapist, was referred to a neurosurgeon at the same hospital, where she had an MRI scan. This revealed a trapped nerve in her lower spine, which required surgery.

The detective was warned there was a risk she would lose the use of her left arm – causing "great anxiety" – but the surgery was successful.

The incident had "exacerbated" a pre-existing medical condition which she may never have known about if it had not happened, the court heard.

The officer was in 'immediate discomfort'

But continuing to feel pain, the officer was referred to another specialist who performed further surgery for a "frozen shoulder", a condition which was "exclusively attributable" to Bearfield throwing her baby at her.

She still does not have full use of her left shoulder and has been left with a six-inch scar as "a painful reminder of what happened".

Bearfield, of St James Close, Hedon, admitted inflicting grievous bodily harm. She had four previous convictions for battery.

Steven Garth, mitigating, told Judge Paul Watson QC, Honorary Recorder of Hull and the East Riding: "I do, with the utmost possible force, suggest to this court it would be possible in this case to stand back from immediate custody and to follow the recommendation of the pre-sentence report, albeit, perhaps, under the authority of a suspended sentence order.

Kirsty was given a suspended sentence

"I submit that this is a highly unusual case. The defendant, as your honour has heard, is 24 years of age. She had the most wretched start to life. Both her parents were heroin addicts and they did not want her.

"She was neglected by them and placed in care when just a toddler. By the age of five she had been placed with 39 different foster carers spread around the country."

Bearfield also suffers from dyslexia, reactive attachment disorder, an eating disorder and has "difficulties" with her spine, Mr Garth said.

Her relationship with the children's father was over, she was the sole carer for them and had proved to be an "excellent mother", Mr Garth said.

She was feeling "upset" and "humiliation", as well as "shock" and "disbelief" at the time of the incident, he said. Mr Garth said the baby was "airborne for only a split second".

Bearfield was remorseful and the children are "thriving", Mr Garth said.

After a short adjournment, Mr Evans told the court that police and social services "retain an interest in the family", and asked the judge if he needed further details of that. The judge said he did not.

Judge Watson said of the officer's statement: "I was, as anybody would be, personally moved to hear of the profound effects this injury caused. They were caused by you."

The judge said he had reflected for some time on the sentence, and although the offence crossed the custody threshold, "I have decided it would not be right or conscionable for something you did two years ago to immediately deprive you of your liberty."

Bearfield was sentenced to 12 months in jail, suspended for 18 months, and must have up to 25 days rehabilitation.
