A young thug tried to throw his ex-girlfriend out of a first-floor window and threatened to stab her dog after he was dumped by text.

Jarron Webb, 22, launched the sustained attack after his partner ended their two-month relationship because he had become overfriendly with one of her pals.

Canterbury Crown Court heard he went to her home in Lucerne Drive, Seasalter, to collect his belongings, but things soon turned violent.

“He tried to make a grab for the victim’s phone,” said prosecutor Simon Taylor. “She hid it behind her back and he took it and started shouting at her in her face and she thought he was going to hit her.”

Webb said he would stab her dog and went to the kitchen and got a large knife.

“The dog was in the bedroom,” Mr Taylor said. “Webb kicked the door open and she heard the dog yelp. Webb came out of the room, threw the knife on the floor and refused to let the victim back in the room so she could see to her dog.”

Webb then opened a window and lifted his victim towards it and went to throw her out of her first-floor flat. She was screaming for help, Mr Taylor said. He pulled her back and calmed down.

In a statement the victim said she had since been diagnosed with depression and had tried to kill herself. She was not eating properly.

Dominic Webber, defending, said Webb’s mother had died two months before the incident.

“He was sad she had died even though she was an abusive alcoholic,” Mr Webber said. “It is in this context that this violent and very frightening behaviour occurred. He is sorry about what happened. It was a one-off which occurred in a very difficult period of bereavement.”

Webb, who lives in Luton and has no previous convictions, admitted assault, making threats to kill and damaging property.

Jailing him for 21 months, Judge Rupert Lowe told him: “I have no doubt that you behaved in part because of what happened to you in the past but at the age of 22 you have reached the point to take responsibility for your actions.”

Webb was also given a five-year restraining order.
