The American suspect's claim comes as Italian police officers who investigated Miss Kercher's murder continue giving evidence at the trial of Knox and co-defendant Raffaele Sollecito.

Knox told the court she had given the same version of events to police for several hours.

But, she added: "I was called a stupid liar. I received slaps to the head, I really did. I'm sorry, but it's true."

Reporting from Perugia, reporter Nick Pisa said: "Trembling and emotional, the American said that she was 'cuffed on the head' at a police station.

"She also said she was told to 'try to remember something else' before blaming the murder on an innocent bar owner, Patrick Lumumba."

Mr Lumumba is bringing a slander case against Knox after he was arrested, held and then released without charge.
