Police are appealing for a woman to come forward who consoled a rape victim shortly after the victim was attacked.
The woman saw the female victim sat on the kerb in a distressed state outside the Showcase Cinema on Hyde Road, Manchester, early on Saturday morning.
The passer-by asked if she was alright and flagged down a taxi before asking the driver to take the woman to Longsight police station.
Police want to trace the "Samaritan" as part of their investigation.
Anyone with information is urged to contact police or Crimestoppers.
