CAIRO Sept 17 (Aswat Masriya) – The slain PhD student, Guilio Regeni's family said they "will not stop working for the investigations to uncover the truth of his killing, the Italian news agency AKI reported on Friday.

"The issue does need [the support of] millions of Italian citizens alone, but many Egyptians as well," the family said adding that "we owe this to Guilio and to the dignity of these two peoples."

A statement by Egypt's prosecution general said earlier this month that the independent Street Vendors Union's head had reported the Italian researcher to the police early January, a few weeks prior to his disappearance and death.

Regeni, who was in Egypt studying the independent street vendors, disappeared in Cairo on Jan. 25, 2016, which marked the fifth anniversary of the popular uprising that toppled former president Hosni Mubarak.

Ten days later, Regeni's body was found, bearing signs of torture, in a roadside ditch on the outskirts of the capital.

Egypt's prosecution general recently headed to Rome amid complaints from Italy about Egypt's lack of cooperation in the investigation into the death of Regeni.
