A frenzied knifeman stabbed repeatedly at his neighbour’s barricaded door while making threats to kill - after being asked to turn down the stereo.

Howard Harris later admitted he would have killed terrified Ian Sherringham, had he been able to smash his way into the Ramsgate home.

Armed with a kitchen knife, the 30-year-old hacked at Mr Sherringham’s front door, minutes after the noise complaint.

Harris was handed an extended five-year prison sentence at Canterbury Crown Court last month after a judge deemed him “dangerous”.

He will only be eligible for release when a parole board deems him safe after at least two-thirds of the sentence.

“When Mr Sherringham attended your flat to ask you to turn down the volume a verbal altercation started,” the judge, Recorder Turner, said.

“Thereafter, you proceeded to call out to Mr Sherringham, saying that he should come outside so that you could stab him.

“When sensibly he did not do so, you seemingly hacked at his front door with the knife continuing your threats to stab him.

“It is by the grace of god you did not in fact cause any physical harm.”

Mr Sherringham managed to barricade his front door as Harris hacked and slashed with the “fearsome weapon”, while shouting death threats.

Eventually Harris disappeared and was arrested shortly after, with officers discovering the blade stashed under a pile of washing up in his kitchen, following the ordeal on the afternoon of October 21.

Harris, who was heavily intoxicated at the time, left Mr Sherringham “shocked and terrified” and “convinced if he broke into his flat he would have killed him”, the court heard.

The criminal initially denied causing the chaos at the sheltered accommodation in Wellington Street.

However, he pleaded guilty to making threats to kill, possession of a bladed article and criminal damage before a trial.

The court heard the pair were well known to each other, with no bad blood between them, however Harris saw red after becoming heavily intoxicated.

Ruling Harris was “dangerous” in the eyes of the law, Recorder Turner explained psychiatric reports revealed he refuses medication for schizophrenia and ADHD, instead using crack cocaine and heroin.

And since being held on remand for about 10 months Harris had been swapping his food for the synthetic drug spice.

Psychiatrists ruled Harris was not in a psychotic state at the time of his outburst and fully aware of his behaviour.

Appearing in a grey tracksuit remotely from HMP Elmley, he appeared fidgety but cordial.

He interrupted the hearing on one occasion declaring: “It’s dinner time.”
