The statement was made to an Italian delegation in Cairo, led by Italian Deputy Chief Prosecutor Sergio Colaiocco.
Colaiocco reportedly left Cairo on Wednesday after a two-day visit to follow up on the Giulio Regeni murder case.
Regeni was a 28-year-old Cambridge University graduate from the northern Italian region of Friuli-Venezia Giulia.
His bruised and battered body was found near a highway on the outskirts of Cairo on February 3, 2016, nine days after he disappeared.
Italian and Egyptian officials conducted separate autopsies on Regeni's corpse with an Egyptian forensic official reporting that he was interrogated and tortured before he was murdered.
More than a year after Regeni’s death, nobody has been charged for the chilling crime.
