The 19-year-old was sexually assaulted early on Friday morning before fleeing. The woman fled a vehicle which had been parked in Yeaman Shore in the city centre after a man walking a dog came to her aid. Police are now appealing for the man, and any other witness to come forward with information on the “terrifying attack”.

       Officers have said the attacker has not yet been arrested, however no description has been released.

       Detective Inspector Sarah Brow said: "This has been a terrifying attack on the woman and she is currently receiving support from our officers.

       "We are keen to speak to the man who was walking his dog who helped her and anyone else who was in the area at the time as any piece of information, no matter how small, can help.

       "We have extra evening patrols in the area and anyone with any concerns should get in touch."

       Withnesses or anyone with information is asked to contact police by calling 101, quoting reference number 0431 of Friday August 27.
