Former prostitute Lindi St Clair has claimed she was attacked by serial killer Steve Wright in the 1980s.
Lindi St Clair said she had reported her claims to the police
Miss St Clair, from Herefordshire, said she recognised press photographs of Wright, who was jailed last week for murdering five prostitutes in Ipswich.
She said he tried to grab her throat after visiting her as a client in London, but she managed to flee.
Miss St Clair, known as Miss Whiplash, was an infamous prostitute in the 1980s who claimed MPs were among her clients.
She said she "went cold" when she saw old photos of Wright from the 1980s, when he worked on the QE2 liner, used in a television news report.
She said: "I recognised the photograph and when you are attacked by somebody you take an instant snapshot in your head of the face.
"He had just come in for regular service and then when he finished he just lunged up at me with his arms outstretched to grab my throat.

"As he did that he said 'I know you, I know you'.
"With that I jumped up and went out the door and ran out into the street."
She added: "I've reported this to the police."
West Mercia Police confirmed they had received information relating to Wright from a woman living in Herefordshire.
A spokesman said the force had passed the information on to the Metropolitan Police but said no formal complaint had been made.
Miss St Clair said she had always taken steps to protect her safety while working as a sex worker, such as carrying alarms and identifying escape routes, and advised other prostitutes to do the same.
Wright was told he would spend the rest of his life in prison after being found guilty of the murders of Gemma Adams, Tania Nicol, Anneli Alderton, Paula Clennell and Annette Nicholls.
