Amanda Knox (L) is comforted by her sister, Deanna Knox (R) during a news conference shortly after Amanda arrival at Seattle-Tacoma International Airport October 4, 2011, in Seattle. US student Amanda Knox arrived home a day after she was acquitted of murder and sexual assault charges and freed from jail in Italy, after a four-year ordeal.

Italian prosecutors want AMANDA KNOX back in jail on murder charges.

In Milan, prosecutor Giovanni Galati filed a 112-page appeal seeking to throw out a court ruling that found Knox innocent of her roommate, Meredith Kercher’s murder. 

Galati said he is "very convinced" that both Knox and her former Italian boyfriend Raffaele Sollecito killed  Kercher, who was found dead in her room with her throat slashed on Nov. 1, 2007.

According to the Italian news agency, ANSA,  Galati charged that the appeals court conclusion had "omissions and many errors."

As The ENQUIRER previously reported the stunning reversal of fortune by the appeal court judges set Amanda free after four years in an Italian prison.

Angrily, Amanda Knox’s family issued a statement, charging Italian prosecutors with “harassment".

"We are not concerned about this appeal as Amanda's innocence was clearly and convincingly proven in her appeal trial," the statement said.

 "This is simply another example of harassment by the prosecution against Amanda and makes this terrible, painful incident continue to go on for Amanda, Raffaele and their families.”
