Police launched an information appeal after a man was assaulted in Epsom on Friday (April 12).

In a statement describing the attack, Surrey Police said that the victim was walking along the stretch of road when two masked men, their faces obscured, mounted the pavement on a motorbike and punched the victim before driving away.

Surrey Police said: "At around 2.30pm on Friday, 12 April the victim was walking along the pavement of Longmead Road towards Chessington Road, when two unknown men on a motorbike mounted the pavement, punched the victim to the back of the head and then drove off.

"The two male riders had their faces covered at the time and were wearing black helmets with black visors. The motorbike is described as a black Kawasaki or black Hyundai sports bike with a partial registration of HJ13.

"It is believed that the bike was travelling in the direction of West Ewell."

The police statement urged members of the public to come forward if they had seen or heard anything to do with the incident to help police with their investigations.

In particular, police hoped that possible dashcam footage from other road users might be helpful to their investigations.

Surrey Police said: "If you were in the area at the time, you might have vital information or dashcam footage which could assist us in our investigation.

"If you live nearby and have CCTV outside your property, you may have caught something."
