A woman has described how she threw himself on to a car bonnet after a man stole a necklace she was selling on eBay.
The victim was selling the Gucci jewellery - worth over £300 - and was approached by a prospective buyer who said he was hoping to buy it for his girlfriend.
Reluctantly, the victim agreed to meet him but when he came to her Bedford house, he snatched the necklace without paying for it.
Shocked by his actions, both the woman and her partner jumped on his car - but he got away - leaving her with minor injuries.
She told Bedford Today: "I tried to stop his car. I was on the bonnet and my partner was hanging on his wing mirror.
"He really was putting his foot down. He didn't give a stuff - and I slid off the bonnet."
The man was described as mixed race, 6ft 3in, short black curly hair, skinny and was wearing a grey hoodie and man bag.
The incident happened on Friday (December 24) at approximately 6.30pm.
