Tonga Yvon Richard was staying at Pokola and in possession with four ivory tusks that he acquired from indigenous people and wanted to sell them. He therefore contacted Mongambo Annicet and sent him XAF 10,000 (ten thousand) to transport the tusks from Pokola to Ouesso and get a compensation. To avoid rangers check points, Tonga Yvon Richard decided to pass through Sangha river with the help of Matoukou Théophile the owner of the boat who thought the boat was for Tonga’s brother. On February 26, 2018, Mongambo Annicet and Matoukou arrived Ouesso and were received by Tonga Yvon who brought them to hotel ”Les Jumelles” to meet the client and sell the ivory. They were then caught by the gendarmerie which arrived to the place, arrested them and brought them to the Ouesso territorial brigade.
