A woman was knocked unconscious after two men ambushed her in her car before attacking her and stealing her bag in a terrifying attack.

At around 10.15pm on Monday, the woman was driving her cream Fiat 500 along Templewood Road towards Stoke Poges when a man jumped out from the bushes and in front of her car.

When the lady thought she had injured the man, she stopped her car to make sure he was not hurt.

A second man then struck the woman from behind, before the first man punched her in the face after she fell to the floor, causing her to temporarily lose consciousness.

When she regained consciousness, both offenders had fled the scene. The victim noticed that her bag had been stolen.

The victim suffered concussion, bruising to the left side of her face and a lump on the back of her neck.

UPDATE: Police confirm manhunt to find the attackers is continuing 

The first man is described as mixed race, aged in his early to mid-twenties, about 5ft 5 inches tall and clean shaven. He was wearing a dark beanie hat, a dark hooded top with a silver badge on the left side of the chest and matching tracksuit bottoms.

There is no description of the second attacker. It is possible that the men left the scene in a black Audi saloon car.

Case investigator Hazel Brown, based at Amersham police station, said: “This was an unprovoked assault that left the victim very shaken.

“Thankfully, despite the nature of the attack, she was not seriously injured, but has had to have time off work due to the concussion that she suffered.

“I am appealing to anybody that was in Templewood Road at around 10.15pm on Monday who believes they may have witnessed this incident or saw the offenders or a black saloon vehicle in the area, to contact the 24-hour non-emergency number 101, quoting reference number 43190106848.
