A woman is said to have been driven to a remote location near Marlow and raped and sexually assaulted.

Police are urging a member of the public - possibly a farmer - who may have witnessed the shocking incident and spoke to the woman between 7am and 8.30am on September 16 to come forward.

The attack was reported to police the same day.

A 36-year-old man has been arrested and charged in connection with this and a separate sexual assault which was reported on March 24 this year in Reading.

In the first incident, a woman who was asleep in bed in a hotel was sexually assaulted.

Investigating officer Detective Sergeant Steve Fox, of Force CID based at High Wycombe police station, said: “We are trying to identify a witness to the second incident, who is possibly a farmer, who spoke to a woman between 7am and 8.30am on Sunday 16 September.

“The area is believed to have been somewhere between Henley and Marlow.

"This witness is urged to contact police, as we believe they may have important information with this to this investigation.

“This person can call 101, quoting reference 43180283696.

“I also believe there was a person walking his dog, and someone on a bicycle between these times on that Sunday who may have spoken to the victim.

“Again, if you believe that was you, please contact 101.”
