Elvis Brown Luma Mukuna is a member of Organic Farming for Gorillas (OFFGO), an organisation that had published information about abuses and disputes linked to land and business operations in Cameroon, in particular by the Baba Ahmadou Group. Elvis Brown Luma Mukuna and OFFGO's founder Jan Cappelle received numerous death threat calls during the months of October 2020 and December 2020. A group of individuals in civilian clothes monitored Mr. Elvis Brown's house during the Christmas and New Year holidays. The callers communicated on October 8 2020 that barrister Elvis Brown ‘will be found', and made reference to what happened to Mr Elvis Brown and his family in 2019 - 2020 (i.e. torture of one brother, attempted kidnappings and a shooting incident). The callers reportedly communicated on December 7 2020 that ‘they are almost finished with Jan Cappelle’, and they ‘will then focus on Mr Elvis Brown’.

Previously, Mukuna had been attacked in 2020, in 2019 and 2018.
