Knox parents indicted for libelling police
Parents of Kercher killer said police hit her15 February, 14:49
"Contrary to the truth", the indictment said, Curt Knox and his wife Edda Mellas told the British weekly in 2009 that their daughter "had not been given an interpreter, had not received food and water and had been physically and verbally abused".
They are also accused of falsely claiming that Knox was "hit by a cuff behind the head" and "threatened (that) if you ask for a lawyer things will get worse for you".
Five members of the Perugia flying squad are standing as plaintiffs in the trial, which will open in Perugia on July 6.
Knox, who has begun her appeal against a 26-year term for murdering her flatmate, is also on trial for libelling police.
Three people have been convicted of murdering Leeds University student Kercher, who was found with her throat slit on the morning of November 2, 2007.
The other two are Knox's Italian ex-boyfriend Raffaele Sollecito, who is appealing a 25-year sentence, and Ivory Coast drifter Rudy Guede, who has exhausted the appeals process and is serving 16 years.
Last month Knox's legal team scored a victory in securing the re-examination of DNA evidence which her supporters say is sketchy.
At the original trial, which ended in December 2009, judges found that Knox, Sollecito and Guede killed Kercher in a drink-and-drug-fuelled sex game that went wrong.
