Now working as a private ­investigator, the ex-officer claimed reporters wanted the victim’s phone numbers and details of the calls they had made and received in the days leading up to the atrocity.

A source said: “This investigator is used by a lot of journalists in America and he recently told me that he was asked to hack into the 9/11 victims’ private phone data. He said that the journalists asked him to access records showing the calls that had been made to and from the mobile phones belonging to the victims and their ­relatives.
