'Red mist' Wakefield ex bit woman's new boyfriend, ripped out his earring and beat him with vacuum attachment

Man saw woman moving on from relationship as a “sense of betrayal”.

A jealous thug said the “red mist” descended as he launched into a vicious assault on his ex partner’s new boyfriend.

Dean Ambler was then held on remand at HMP Leeds over the unprovoked attack in Normanton.

The 39-year-old admitted ABH and criminal damage and was freed this week after being given a suspended sentence, but was warned to stay away from his former partner.

Leeds Crown Court heard that Ambler had gone, with a pal, to the woman’s home on April 5, and let himself in through the unlocked back door.

He went upstairs where he encountered the woman’s new partner and launched into him.

He punched him and a struggle ensued. Ambler picked up the metal vacuum attachment and struck the man with it.

He bit his thumb and ripped out his earring.

The man was able to get into the bedroom and lock himself in, before Ambler tried to smash down the door.

The police were called but Ambler had left before they arrived. He was later arrested and gave a largely no-comment interview.

He has 17 previous convictions for 24 offences.

Mitigating, James Holding said Ambler had both accomodation and a job to go to - working as a fibre broadband installer.

He said: “He succumbed to the red mist. He accepts wholly now he is separated and she has a right to see another man.”

He said Ambler, of Chestnut Crescent, Normanton, saw it as a “sense of betrayal” at the time.

Mr Holding said that despite having violence on his criminal record, he had not committed such offences for 10 years.

Judge Christopher Batty told Ambler: “We both know what this was about. You did not like the fact you thought you had been betrayed.

“What followed thereafter was a sustained attack.

“You are lucky he was not more seriously injured than he was.”

He gave him a 10-month jail sentence, suspended for 12 months, with 100 hours of unpaid work complete, along with 25 rehabilitation days with probation.

He was also given a 120-day alcohol-abstinence monitoring requirement and a five-year restraining order to keep him away from his ex and her address.
