The inquiry has widened to encompass alleged sexual misconduct and corruption offences
Thames Valley Police has denied any claims that it is "struggling for evidence" in the Andrew Mountbatten-Windsor inquiry.
Mr Mountbatten-Windsor was taken into custody in February on suspicion of misconduct in public office connected to his former position as a Government trade envoy.
The inquiry has now widened to encompass alleged sexual misconduct and corruption offences, all falling under the umbrella of misconduct in public office.
Detectives have issued a public appeal for victims to come forward, stressing that the charge represents "a crime that can take different forms".
Witness interviews are understood to have already taken place.
A policing source had previously told the Times: "They are struggling to get the evidence they need, which is why they've broadened their appeal."
However, a spokeswoman from Thames Valley Police clarified to GB News: "Misconduct in public office is a crime that can take different forms which is why we have sought to explain this and address any misunderstanding about its scope.
"An appeal for witnesses and information is standard procedure in criminal investigations and is just one of the large number of lines of enquiry being pursued as part of our fair and thorough investigation."
Mr Mountbatten-Windsor was arrested on his 66th birthday on suspicion of misconduct in public office.
The King's younger brother was released on investigation, and has consistently denied any wrongdoing.
Following Mr Mountbatten-Windsor's arrest, King Charles issued the following statement: "I have learned with the deepest concern the news about Andrew Mountbatten-Windsor and suspicion of misconduct in public office.
"What now follows is the full, fair and proper process by which this issue is investigated in the appropriate manner and by the appropriate authorities. In this, as I have said before, they have our full and wholehearted support and co-operation.
"As this process continues, it would not be right for me to comment further on this matter. Meanwhile, my family and I will continue in our duty and service to you all."
