Full-scale investigations have been launched into activities at the Hosea Kutako International Airport after it was determined that the 18 rhino horns that a Chinese national was found in possession of in Johannesburg, were detected by scanners at Hosea Kutako International Airport. However, even though the scanners detected the rhino horns in the luggage of Ye ZhiWe, 28, who was in transit from Windhoek to Hong Kong, he was still allowed to board a South African Airways flight bound for Johannesburg.
