A £5,000 reward is being offered for information about two sex attacks on young girls in Claygate and Ewell that police believe are related.

On July 10 at about 4.30pm, a man pushed a 15-year-old girl off her bike by the Hogsmill River estate in Ewell and sexually assaulted her.

She fought him off by biting and scratching him in the incident, near the King George V Recreation Ground, and he ran off in the direction of Ewell.

At about 5.50pm on August 17, a 10-year-old girl was sexually assaulted in the woods parallel to Foxwarren, in Claygate, while she was walking to her friend’s house, and she also managed to escape.

Police believe the two girls were attacked by the same man.

In CCTV footage previously released, a man is seen at about 5.18pm on the day of the Claygate assault walking down Steven’s Lane towards Claygate centre. He was wearing a distinctive blue Chelsea FC jacket and a black cap with a Ferrari logo.

These items were then found discarded the following week in Berkley Gardens.

The man is described as having a tanned complexion, possibly Asian or eastern European; with short, dark, collar-length hair; a full black beard; a medium build and being in his late 30s or early 40s.

Crimestoppers is offering a reward for information given directly to them on 0800 555 111 or at crimestoppers-uk.org that leads to the arrest and conviction of the person responsible.

Roger Critchell, director of operations at Crimestoppers, said: “We believe everyone has the right to feel safe from crime. These attacks are shocking and we’ve put up this £5,000 reward to encourage anyone who may have information to contact us 100 per cent anonymously.

“We’re a charity that gives people the power to speak up to stop crime. We won’t ask your name and we won’t judge. We’ll just listen to what you know. When you hang up the phone or click send that’s it and no one can trace you. Even if you think what you know might be insignificant, it’s worth letting us know.”
