A drunk thug carjacked a terrified woman as his young son watched on traumatised and begging his dad to stop.

Roger Porter stepped in front of his frightened victim’s Ford Galaxy and screamed “get out the ******* car” in High Street, Deal.

The 37-year-old threw the woman into the road and then drove away in car, which she had bought to help her disabled son.

It was later found dumped about half-a-mile away.

Porter, from Deal, was jailed at Canterbury Crown Court after previously admitting robbery.

The court heard that on Monday, March 13, Porter had downed six pints of beer and double shots, having recently been released from a spell in prison.

At 6pm that evening, he blocked off the car’s path and repeatedly and aggressively demanded the woman get out of the vehicle, but she refused.

Porter opened the car door and grabbed hold of her seatbelt with such force it caused pain to her neck, the court was told on April 21.

But as the woman unclipped the belt to defend herself, Porter grabbed her arm and threw her to the pavement.

Porter’s child could be heard shouting “Dad, that’s my dad, stop it dad” as the violence unfolded, prosecutor Ben Wilde said.

Handing down three years in custody, Judge Simon Taylor KC told Porter: “You can only imagine being dragged from your car in the early afternoon - you can only imagine how terrifying that would be.”

The judge emphasised Porter had ordered a lone woman to get out of the car in front of his own traumatised child.

Porter was arrested at his home shortly after the robbery. The stolen car keys were found hidden on top of a cupboard.

“You can only imagine being dragged from your car in the early afternoon ... how terrifying that would be...”

Meanwhile, the Galaxy, which cost about £1,800, was found dumped and written-off in West Street.

Magdalena Biglou, mitigating, said Porter had recently been released from prison for a previous offence and had “no recollection” of the robbery.

Porter believes his actions arose after not receiving medication for his mental health and having consumed a high quantity of alcohol after a period of sobriety.

Porter, who appeared remotely from HMP Elmley, sent the judge a letter, saying: “I’m so remorseful. I can only imagine how traumatic this was.

“I can’t imagine what that lady feels like. She might not want to go out anymore. I am disgusted. I know I have to be punished.”

Porter, of High Street, pleaded guilty to one count of robbery at an early opportunity.
