Police have released images of a man they want to speak to in connection with two linked sexual assaults on young girls.

A man pushed a 15-year-old girl off her bike while she was riding in the Hogsmill River estate in Ewell on July 10 at around 4.30pm, then he sexually assaulted her.

She fought him off and ran to safety.

On August 17 at around 5.30pm to 5.50pm, a man sexually assaulted a 10-year-old girl in a wooded area in Claygate while she walked to her friend’s house.

She also managed to break away from the man and escape.

Police are linking the two incidents, and now wish to speak to the man in the images.

The CCTV stills show a man in Stevens’ Lane, Claygate, at the junction of Hill View Road, the entrance to Ruxley Heights private estate, near to Berkeley Gardens on August 17 at 5.53pm, then in Stevens’ Lane towards Chessington at 5.56pm.

Detective Chief Inspector Jo Hayes, from the Surrey and Sussex major crime team, who is leading the investigation, said: “We need to identify this person as soon as possible. If you know who he is or if this person is you, I urge you to contact police either by calling 101 or attending your nearest police station. You can also report anonymously through Crimestoppers.

“We have DNA of the man we’d like to speak to so can easily rule people out of our enquiries from any names provided to us. Enquiries remain under way and it is only a matter of time until we find the person responsible for these attacks.

“The two incidents have understandably been very concerning for the local communities and are being investigated as a priority. We have had a great response from members of the public to our previous appeals and I would like to thank everyone for all their assistance so far.

“Local neighbourhood teams are continuing with enquiries around the areas concerned and officers have also increased patrols in the vicinity of both assaults.”

Anyone with information is asked to call Surrey Police on 101 quoting reference 45170090450, or call Crimestoppers anonymously on 0800 555 111.
