Machete attacker Michael Mankelow shouted 'I will have justice - I know where you live' at a judge as he was led away to start a lengthy jail term.

His outburst came as he was sentenced to 10 years in prison by Judge Adele Williams at Canterbury Crown Court.

She told Mankelow he had launched a “frenzied attack” on PC Matthew Bilney and had been convicted on clear and compelling evidence of attempting to cause him grievous harm.

She told him: “This was a sustained and repeated attempt.”

Judge Williams said she was sure Mankelow knew that PC Bilney was a police officer when he and a colleague called at Mankelow’s house in Downs Road, Walmer on February 4, even though he was not in uniform.

She added: “You came to your door armed with a hunting knife. You then came out of your house with the knife and launched a frenzied attack on the police officer. He was, rightly, terrified and feared for his life.

“I have no doubt that had he not been able to start his car you would have caused him serious injury.

“These police officers were doing their jobs and had no idea on that morning that they would be met with such extreme violence. They are to be commended for their actions.”

Judge Williams said that Mankelow, 58, had run over a man in 1983 and broken his legs and had also threatened to kill a High Court judge.

She added: “You are, in my judgement, a man who will not accept authority.

"You have shown no remorse and no insight into your offending. You still regard yourself as a victim” - Judge Adele Williams

"When you lose your temper in these circumstances it leads you to use extreme violence.

"You have shown no remorse and no insight into your offending. You still regard yourself as a victim.”

Judge Williams told Mankelow that when he was released he would be on licence for two years.

But he would only be released if the parole board considered it was safe to do so.

Oliver Saxby QC, defending, said Mankelow’s most serious previous conviction dated back to 1983. The incident with PC Bilney happened over a short timescale.

He added: “It is an example of someone with a short fuse losing his temper but not in a premeditated fashion.”
