More than two years after the biggest rhino horn smuggling case in Namibia was uncovered, the defence rested on Tuesday after the alleged kingpin that was pulling the strings in Namibia took the stand. The case, which involves four Chinese nationals Li Xiaoliang, Li Zhibing, Pu Xuexin and Wang Hui, was postponed in the Windhoek Regional Court for closing arguments on 20 May. The four men were arrested for trying to smuggle 14 rhino horns worth more than N$2.3 million and a leopard skin valued at N$50 000 out of Namibia. The items were found in two luggage bags at Hosea Kutako International Airport on 24 March last year.
