Detective Sergeant Cerith Jones said: “The community will be appalled by this awful incident and I know many people will want to reach out and help us identify them.

“I urge local people to please check your doorbell and dash cam footage for any material that could assist us. If you were in the vicinity and saw two men acting suspiciously, or running away, we want to hear from you.

“The young woman was terrified and it is imperative that we catch the men responsible.”
