Yes "legal fraud police" does very much read like a freeman of the land guff, as does "we in line with the growing national concern, are creating local inquiries and grand JURY's" (sic)
In case the flyer is deleted again (identifying details have been removed, but the photo of the elder daughter is still unredacted), precis is that it is an appeal for information about "unlawful attempt to steal a local child" and the page with her photo is titled "missing" and captioned "has your child been targeted and taken by the local authorities?"
It's a little muddled - even though it says "emergency update 7/10/23" it reads as though it was written on/around 7 September (when police visited the aunt, who telephoned Clive - both parents still in Grenada at that point - to let him know)
(NB: newspaper story about their difficulties with the authorities re birth certificate following birth on yacht and move from St Lucia to Grenada was published mid-August. At that stage, they were awaiting DNA results which were required to establish claim to British nationality as none of the usual supporting documents required for that existed. So these events were nearly a month after that)
Some time after that, Clive had a telephone conversation with the police (confusing account provided)
On 15 September, she was "forcibly kidnapped from the arms of her dad"
(so he must have been in the country then.
Various allegations of quite strange police actions re their property and their animals, lasting over 8 days (not clear what date/s)
Refers to the father as Clive, and the contact phone number is for Chris.
