Callum Hutton broke into the property and armed himself with a knife in the middle of the night as the woman, her new partner and their children were in bed.

A court heard how the adults and children tried to barricade themselves into a bedroom at the property in Wakefield.

Hutton, 22, managed to kicked through the door to get into the room where he fought with the other man as the youngsters screamed in terror.

Leeds Crown Court heard Hutton also attacked the woman in front of her children outside their school on a separate occasion.

Hutton was jailed for 35 months after pleading guilty to a series of offences in October last year

Anthony Moore, prosecuting, said Hutton breached a restraining order by turning up at his sister's home in Normanton on October 7 and demanded the mobile phone number of his former partner.

Hutton shouted abuse at his sister when she told him she did not have the number.

He said to his relative: "You better f****** ring her and tell her I'm going to set her house on fire."

Hutton walked into his father's home five days later armed with a knife and demanded his car keys.

The defendant had been the subject of a restraining order banning him from contacting his father but it had expired at the time of the incident.

Hutton told his father he needed his car and was going to kill his former partner.

Later the same day Hutton "stormed" into the Junction pub in Normanton and smashed glasses before throwing a drink over a woman who is a friend of his former partner.

Hutton attacked his ex-partner on October 22 as she was about to take her children into school.

The defendant grabbed her by the hair and dragged her around as she was about to get her children out of her car.

She suffered a cut lip during the incident.

Hutton also kicked the woman's car, causing dents to the vehicle.

Shocked members of the public who witnessed the attack contacted police.

An Iceland delivery driver stopped his van to try to intervene but Hutton attacked the vehicle, damaging a wing mirror.

Hutton then targeted the woman's home in the early hours of October 26.

Mr Moore said her new partner and his daughter were at the property at the time along with her children.

They were woken at 4.25am by banging on the bedroom window.

Police were called but Hutton managed to smash his way into the house on the ground floor.

The adults and the children gathered together in a bedroom and tried to block the door but Hutton kicked his way into the room.

There was then a struggle between the two men.

Hutton had a small blade in his hand and the other man suffered a cut to his finger as he managed to pin the defendant to the ground.

Hutton said to the woman: "You said you would not bring another man in to my daughter's life.

"You better watch your back. You are going to get it."

Hutton, of Wesley Street, Wakefield, pleaded guilty to breaching a restraining order, possession of a bladed article, two counts of common assault, two of criminal damage, assault occasioning actual bodily harm and affray.

Richard Canning, mitigating, said Hutton had struggled with mental health problems.

Mr Canning said his client had been seeing a psychiatrist while on remand in custody and had been diagnosed with a personality disorder.

He said: "He wants to change his life. He doesn't want to be in and out of prison. If he offends in this way again, longer sentences will follow."
