Our client, a UK human rights charitable organisation, was seeking to make a case to present to the UK Government (HM Treasury) for the imposition of sanctions against members of the former regime under José Eduardo dos Santos of Angola. iSanctuary was instructed to undertake a financial investigation to establish whether specific individuals had real estate in the UK which, if confirmed, would strengthen the case for the imposition of sanctions by the UK against the individuals in question. We undertook extensive research in relation to the persons against whom the sanctions were being sought, utilising financial investigation skills to analyse corporate relationships and open-source intelligence (OSINT) research, including mapping and geo-location analysis to identify potential properties being used/owned by the subjects of the investigation. We identified several high-value London properties linked to one of the subjects; the information we gathered enabled the client to present a compelling case to HM Treasury for consideration.
