A rampaging fitness instructor knifed a woman in the face then held a "child hostage" before trying to slash a police officer while drunk and high on cocaine - a court has heard.

Stewart Goodwin, from Basildon, rammed a moped driver off the road then trying to mow his victim down when he launched the attack.

Three months after trying to use his car as a weapon, the "dangerous" 33-year-old slashed his victim's chin, grabbed a child and barricaded himself into the room of a house in Folkestone, Kent.

It took multiple attempts for officers to subdue him in what was described as a "rampage" last may.

A total of four officers forced the door when "well-built" Goodwin shouted incoherently and repeatedly tried slashing PC Davis with a kitchen and flick-knife.

The brave officer parried his blows with a shield and then Tasered Goodwin to the floor, as his colleagues then tried rounding on the crazed knifeman.

But as he was on drink and drugs, Goodwin was able to strip off the Taser barbs before lunging into another assault, kicking and head-butting officers until he was finally restrained.

The woman suffered a deep 3 inch (8cm) cut to her chin, felt too weak to walk and bled profusely, she still suffers facial numbness and could be scarred for life, a court heard.

At Canterbury Crown Court Goodwin pleaded guilty to wounding with intent, actual bodily harm, child cruelty and four counts of assaulting an emergency worker at a previous hearing.

During his sentencing hearing on Friday where he was jailed for nine years, prosecutors told how Goodwin was released under police investigation three months before the attacks last May for using his car as a weapon on another victim.

In a fit of road rage, he drove his Vauxhall Insignia twice into the back of a moped, destroying the vehicle.

His victim fled to a group of nearby workmen when Goodwin accelerated towards them and smashed into a barrier after they jumped out of the way.

As the evidence was read to the court Goodwin, could be seen holding his head in his hands over video-link from HMP Elmley.

He told the hearing that in retrospect the evidence was "too hard to listen to".

But Judge Rupert Lowe told Goodwin using his car as a weapon took road rage "to a whole different level".

He added: "You drove into him using your car as a weapon impacting his moped twice, and on the second occasion knocking him off.

"He ran away, it appears you further pursued him in your car."

Speaking of Goodwin's female victim, he added: "Exactly three months later you committed the more serious offences.

"Having threatened to cut her, you then cut her with the knife, slicing her across the chin causing a deep cut that caused nerve damage and bled profusely."

The judge added Goodwin had essentially "taken the child as a hostage".

James Burke defending said Goodwin tried to "steer a meaningful course in society" after qualifying as a fitness instructor.

The court heard Goodwin, who has racked up 24 previous convictions, suffered a traumatic childhood as he was raised in care where he was diagnosed with conduct disorder, which later developed into mixed personality disorder, substance abuse and paranoia.

But Judge Lowe said Goodwin posed a public risk, deemed him "dangerous" and handed out an extended sentence.

Goodwin, who also pleaded guilty to dangerous driving, was sentenced to eight months in jail for the driving offence running consecutively with a nine-year extended sentence for the violent attacks.
