Now La Repubblica has reported that Eitan's maternal grandfather, Shmulik Peleg, travelled to Pavia to see Eitan for a day visit last week but failed to return him to his Italian guardians in the evening.
According to the newspaper, Mr Peleg then severed contact with the Italian family, aside from a text message that said, "Eitan is back home”.
"We are upset and incredulous that they have gone this far," Armando Sibari, the lawyer for the Italian side of Eitan's family, told La Repubblica.
"He was literally torn away in an international kidnapping from the family that had been identified by the judge as the most suitable for him to grow up with because it was the one he had always seen daily. We are very worried about the trauma that this act risks causing him," Mr Sibari added.
Eitan suffered severe injuries in the cable car crash but was saved by his father, Amit, 30, who used his own body to cushion his son’s fall.
He was placed in a medically induced coma but regained consciousness after several days and eventually made a full recovery.
