A £5,000 reward is being offered after a woman was attacked and her engagement ring stolen in front of her young son.

The woman had just got out of her parked car in Clarendon Road, Notting Hill on September 29 at 6.24pm when she was attacked, leaving her with a swollen face and a damaged eye socket requiring hospital treatment.

Shortly after the incident, which happened in front of her young son, she realised the people who attacked her had taken her diamond engagement ring, earrings and her bag with her mobile phone, credit cards and money.

The suspects are believed to have fled the scene in a silver car parked at the nearby St Johns Garden/Clarendon Road junction.

The platinum engagement ring has a large square diamond surrounded by smaller diamonds and more smaller diamonds on the band.

Police previously issued an appeal to find her attackers but there is now a £5,000 reward for information leading to the arrest and prosecution of those responsible.

The suspects are described as black men, both 5ft 9ins tall, with one being 20 to 35 years-old and the other about 20 to 30-years-old. Both were wearing dark coloured hooded tops, dark trousers and trainers.

PC Matt Dixon said “A young boy witnessed his mother being subjected to a horrific attack by two men, leaving her and her family with physical and emotional pain.

“We are very keen to speak to anyone who may be able to assist us with this investigation and catch the people responsible.”

Anyone with any information is asked to contact PC Matt Dixon on 020 8246 0173 or call Crimestoppers anonymously on 0800 555 111.
