I have just got home from a local police station. The person I supported was arrested in the early hours of the morning, then this morning had the police interview that I was supporting was released on police bail after pending further enquiries.
A Voluntary police interview in the UK allows a suspect to to attend a police station by consent, without being arrested. Wheres a "Detained" Interview follows an arrest where freedom to leave is removed. Both involve police caution, legal representation and potential charges. Voluntary interviews are usually less intrusive, the interviewee is free to leave at any time but both carry the same risks. If someone does not attend a V interview after the police have invited them, or they leave and do not engage in the V interview they will be arrested, charged and made subject to detained interview.
AMW has had months to take legal advice and for himself or his legal rep to offer him coming in for a police interview. It is publicly known he has not done this and that neither has he responded to US authorities to similarly attend the uS equivalent of a Voluntary interview.
As a result of Andrew not coming forward voluntarily to date ( the police had little to no potential evidence of misconduct in public office until Epstein files' release to arrest) and in context of the seriousness of the allegations, the inevitable massive public scrutiny and the necessity for the Police Force to be shown to be acting fairly, he can absent himself from the country easily, and in the Public Interest- it seems logical to arrest him on suspicion. No one is given notice of date and time of arrest in such circumstances. There is no separate law or change to any process for members of the Royal family. The extent of any difference perhaps is that a custody suite has been chosen that no other detainees might be present. Custody suites and holding cells can be busy, noisy places. DP's at any time may be under the influence of drugs and alcohol and calling out expletives, acting up, self harming etc.
On arrest in the UK the police must specify the nature of the suspected offence and the grounds for the arrest to have the jurisdiction to detain and interview someone. They do not need to "formally charge" a DP at this initial stage. or provide a final, legal definition of the crime- it is a process to provide opportunity for the DP to give their account of alleged crime/s and to show their hand on the evidence they have to date. It is the choice of the DP, on advice of solicitor whther they give a no comment interview or are open, answer questions, share documentation in their possession to help the police with their enquiries etc.
On arrival at the police station the Detained Person ( DP) is processed by the custody Sergeant: personal details, health, medications, whether ever self harmed, thinking of it now, needs to see a health professional etc. They will have their rights read to them and offered a written copy. The DP will be asked whether they want anyone to be informed that they have been arrested and detained and if they would like free legal representation ( Duty Solicitor) or would like the custody sergeant to call a legal representative of the DP's choice. I would imagine AMW asked for someone in his family to be informed and to ask them to secure a Solicitor of his/their choosing and they would pay for that.
The DP then waits for Solicitor to arrive- in a police cell- offered food and drink as appropriate. When Solicitor arrives in police station they have meeting with the officer in charge of the investigation (OIC) called "disclosure" The police thus show the solictor what evidence they have so far gathered in their investigation. Solicitor then meets with DP ( officers will get them from their cell), their client, and gives legal advice.
Interview takes place under police caution, taped and recorded. The DP person will be asked 3 questions to make sure they understand the caution:
1) do you have to answer my questions today? answer no- as have right to be silent or say no comment,
2) However if you dont answer my questions today, and if this matter later goes to court, and you say something then in your defence, that you didnt say today, what might the court think? A less likely to believe me.
3) How will the court know what is said today? Recorded audibly and visually.
