“He just came up and just whacked me, he whacked me on the cheek,” she said.   “He said nothing. I thought he was going to ask me for something when I saw him because he just seemed to come from nowhere.”

Terrified, Mrs Dillon gave the attacker the keys. He then sped off in the green 1996 Hyundai Excel hatch, almost running Mrs Dillon over.

“He said, ‘Give me, give me’, and I didn’t know what he was talking about. He wanted the car keys. And I was saying no,” she said.

After being knocked to the ground, Mrs Dillon said, she struggled to get back up. After that she found it difficult to get help.

“It was daylight, broad daylight,” she said. “Nobody would stop. When I got up finally, I stumbled to the edge a bit and a car was coming and I waved at him and, no, he didn’t stop.”

Lying in hospital on Monday with broken bones and covered in cuts and bruises, including two black eyes, Mrs Dillon said she had struggled to sleep since the attack.

She didn’t want to say what she would tell her attacker if she came across him again.

“Every time I close my eyes, I can see him coming at me,” she said.

Police say the car, registration OYI793, was last seen headed north-east on Stradbroke Drive in St Albans and is yet to be found.

The man is described as Caucasian, aged between 20 and 30, clean shaven and wearing dark clothing.

Mrs Dillon was taken to hospital with serious injuries but is in a stable condition.
