Luke Allman, 26, was out celebrating after the gender of his first child was revealed when he kicked off with staff at Bask, near Stockport station, and screamed: "I'm going to f***ing kill everyone"

A man celebrating the reveal of his first child's gender stabbed a doorman after downing 10 pints and taking a 'modest amount' of cocaine.

Luke Allman caused a scene at Bask, near Stockport station, on February 23 this year, shouting: "I'm going to f***ing kill everyone."

He was standing in a 'no service' area when he threw a sign and was asked to leave. The 26 year old was 'violently ejected', Minshull Street Crown Court heard, with him and two security staff getting injured in the ensuing scuffle.

CCTV footage showed Allman landing on his back before walking away. However, 12 minutes later, he returned armed with a flick knife and stabbed a doorman who wasn't involved in the initial altercation.

The doorman was left with a protruding bowel from an abdominal wound and had to undergo emergency surgery. Allman has now been sentenced to nine years in prison after pleading guilty to causing grievous bodily harm with intent; assault occasioning actual bodily harm; and possession of an offensive weapon.

The court heard that Allman was out celebrating following a gender reveal for his first child. He had been drinking with friends at a Wetherspoons before moving to Bask, which has since changed management and been rebranded, reports the Manchester Evening News.

Prosecutor Sara Haque said Allman stood in a 'no service' area of the bar, complaining: "I've been waiting here for ages."

When a staff member showed him a sign indicating customers would not be served in that area, he threw it.

Allman was told to leave, before becoming embroiled in a 'big scuffle'. A female security guard was sick after her head was struck.

Allman subsequently returned and attempted to gain entry.

"It's alright pal, I just need one minute," he declared as he was informed no additional customers would be allowed in. He then 'lunged' at a doorman and appeared to strike him, the court was told.

It required four security personnel to restrain him and remove the knife from his possession. "I'm going to f***ing kill everyone," he declared.

Staff then discovered the bouncer had been stabbed in the stomach. Another member of staff was struck around the head and sustained an injured thumb.

He subsequently informed police he 'got pis**d' and was 'bashed up'. Allman claimed he believed the knife was 'legal' because the blade didn't 'look that big'.

In a statement read to the court, the bouncer who was stabbed, said he thought he was going to die, adding: "I'm normally quite active, but after that moment I am wary of my surroundings and look around a lot more. When people are around I'm scared, worried and anxious. I don't want to return to door work due to the risk to my safety and other people."

The female door staff member who was injured said she was admitted to a psychiatric hospital for two weeks. "I've never been so scared and embarrassed in my life," she added.

"This stupid, unnecessary incident changed my life forever."

Henry Blackshaw, in mitigation, described the incident as a 'disaster' for the victims, Allman and his family. "He was inebriated, I spoke to him earlier today and he doesn't have a clear memory," he added.

"He had at least 10 pints of beer and had taken a modest amount of cocaine. We say he was moved in a very heavy handed way and the use of force was unnecessary. He was flung out on his back. Physically hurt, and feeling a sense of grievance at the way he was handled, he wanders up the road and makes the drunken decision to return with a knife and attacks the nearest member of door staff."

Mr Blackshaw stated that Allman held 'no grudge' against the man stabbed, saying he was just 'the nearest person there'. Judge Maurice Greene commented: "There was some provocation, you were violently ejected. That is limited mitigation as less than a quarter of an hour later, you went back and exacted retribution to the nearest doorman you could find.

"He was in the wrong place at the wrong time."

Allman, of Lambeth Grove, Woodley, Stockport, was sentenced to nine years in prison.
