Police have launched an investigation into a rape in Ellesmere Port.
The victim, who is in her 30s, was attacked during the early hours of Saturday, September 24.
Four men – aged 29, 31, 36 and 38 – were arrested on suspicion of rape but have all been bailed pending further enquiries.
Now Cheshire police are appealing for the public's help.
Bid to find 'kind' man who helped her
The force is particularly keen to track down a 'good Samaritan' who identified himself as Graham to the victim when he came to her aid.
'Kind' Graham had seen she was extremely distressed as she made her way home from a property on Whitby Road between 3am and 3.30am on September 24, and made sure she got home safely.
DC Joanne Wilkinson said: “We are really keen to speak to Graham as we believe he can help us with our enquiries.
“Graham was a kind man, who helped the victim when she was very vulnerable.
“We want to stress that we are not implicating Graham in any offences.
"We want to see if Graham can provide us with any vital information that can help achieve us justice for the victim.
“I urge Graham to come forward and contact me. Anyone who may know Graham, or have information that can help with our enquiries, should contact on 101 quoting incident number 994 of October 10, 2016."
Alternatively, information can be given anonymously by contacting Crimestoppers on 0800 555 111.
