SURREY Police is appealing for witnesses after a robbery at the Nationwide building society on Church Street in Walton-on-Thames last night.

A group of people forced their way into the building around 11.30pm, before threatening a security guard with weapons. The group stole £2,500 in cash and fled the scene in a black or dark grey Audi RS6, which was later found abandoned in Chertsey.

The group were described as wearing all black clothing and balaclavas.

Detective Constable Marita Wells, who is investigating the case, said: “This was an incredibly serious incident which will no doubt have left the local community concerned.

“We are working at pace to identify and apprehend the suspects and local residents will notice a continued police presence in the area whilst we carry out our enquiries.

“If you have CCTV covering the area, or if you were in the area at the time and may have information which could assist our enquiries, please contact us straightaway.”

Anyone with information can contact the police by calling 101, or if you do not wish to speak to police, call independent charity Crimestoppers on 0800 555 111.
