A THUG who carjacked a terrified young woman who had stopped to help him has been jailed for five-and-a-half years.

Mark Allgood, 31, attacked the married teacher and stole her £10,000 Audi A3 after he had ploughed his own car into a ditch.

The brute chased the Good Samaritan and viciously kicked and punched her before stealing her car keys and speeding off.

The teacher's burnt out grey hatchback was found dumped hours later, a court heard yesterday.

The terrifying attack happened on the A141 in Huntingdon, Cambs, at the roundabout joining roads from Wyton, March and Abbots Ripton at 8pm on March 4.

Craig McDougall, prosecuting, told Peterborough Crown Court how the woman, in her 20s, had been left distraught and deeply affected by the carjacking.

She went to help Allgood after seeing him smash his Vauxhall Vectra into a ditch.

The woman, who has not been named, pulled up immediately nearby to phone the emergency services.

Mr McDougall said: "She was alone, in shock and concerned for her own safety, but nevertheless she stopped to help."

Allgood clambered out of his wrecked motor and got into the woman's car.

"Once inside the car he said 'drive, you've got to drive me'," said Mr McDougall.

"She replied: 'no, no, I'm not going to drive you'.

"She took the keys out of the ignition, got out of the car and ran away as fast as she could screaming 'help me' - he gave chase shouting 'shut up'."

Mr McDougall said the terror-stricken woman fell onto the grass verge as she tried to escape.

Allgood jumped on top of her and demanded her keys as he brutally punched her on the body and kicked her legs.

The petrified woman gave the thug her keys and he sped off so fast he almost caused another accident, the court heard.

The Audi was found gutted at Millfield Football Club in Needingworth at 10.45pm that night.

Stephen Hopper, defending, said there was "absolutely no excuse" for Allgood's actions.

But he said he had shown remorse and written a letter of apology to his victim.

Jailing Allgood for a total of five-and-a-half years, Recorder Sean Enright said: "This was a very unpleasant offence that you committed in a panic."

Allgood was jailed for four-and-a-half years for robbery and one year for driving the stolen Audi dangerously.

Det Insp Ian Simmons, who led the police investigation, said after the case: "I am extremely pleased with the sentence.

"This was a nasty and unprovoked attack on a young woman who had stopped to help a man she believed to be in trouble."
