The Metropolitan Police is separately investigating allegations linked to Mohamed Al Fayed and those suspected of facilitating his offending.
It said it was one of the largest and most complex investigations it was currently undertaking.
“Seven suspects have so far been interviewed under caution on suspicion of offences including aiding and abetting rape and sexual assault, assisting the commission of sexual offences, and human trafficking for sexual exploitation,” a Met Police statement said.
“To date, 168 victims have now come forward. We will continue to assess victim testimonies for evidence of human trafficking.”
In a confidential note, shared with survivors, of a meeting between the Met and the All Party Parliamentary Group (APPG) for Survivors of Fayed and Harrods, it said about 70 people had been referred to the Home Office as potential victims of trafficking.
Jill told BBC Scotland she was aware of other women who alleged they were abused by Salah Fayed in Scotland, although some have never reported their experiences publicly.
She said she agreed with calls from some of the victims for a statutory public inquiry.
And she said she was speaking out because of worries the police investigations were not looking far enough.
