A woman was raped in an alleyway in Crawley early yesterday morning (Sunday, Oct 24) in the area of Tuxford Close and Atkinson Road.
The victim, who is 30 years old, is being supported by specially-trained officers while police investigate the assault.
They're hoping someone picked up footage on their doorbell camera or dash cam that might help identify the suspect as being in the area at the time.
Anyone with information is asked to contact police online or by calling 101 quoting Operation Rushlake.
Alternatively, you can contact the independent charity Crimestoppers anonymously on 0800 555 111.
