A West Midlands policewoman has no memory of being catapulted into the air by a fugitive's getaway car, the Old Bailey has heard.
Det Con Catherine Corbett, 40, suffered a severe head injury after she was scooped up and thrown into the air by the open passenger door of Rashpal Singh's car.
She was left unconscious on the ground as Singh drove off from outside a hotel near Heathrow airport after leaving two other officers with minor injuries and damaging police vehicles, in November 2007.
Det Sgt Simon Smith told the court that he and other West Midlands police officers had lay in wait for Singh who was on the run from prison after being jailed for fraud.
He said: "The defendant put the car into reverse gear and accelerated backwards at speed without any reference to who was around or behind him.
"As he went backwards the door of the vehicle caught Dc Corbett in the chest, scooped her up and threw her backwards."
He said Dc Corbett was still unconscious when she was taken away by ambulance.
Judge Jeremy Roberts told the jury: "She never has regained any memory of this incident so she will not be called as a witness."
Singh, 43, of Gladstone Street, West Bromwich, denies causing grievous bodily harm with intent, two counts of actual bodily to Dc Matthew Willward and Dc Stefan Wojcieszyn, and dangerous driving.
After being recaptured, he said he did not realise the trap had been set by police and claimed he drove off because he was in fear of his life.
The trial was adjourned to Monday.
