Secret footage obtained of the wild elephants sold into captivity in Chinese zoos

Animal welfare advocates have filmed some of the wild elephants captured in Zimbabwe last year and shipped to China

Last year more than 30 young elephants were captured from the wild in Zimbabwe and flown by plane to China. The elephants - some reported to be as young as three - were dispersed to a number of zoos throughout the country, including the Shanghai Wild Animal Park, the Beijing Wildlife Park and the Hangzhou Safari Park, according to conservationists.

But what are their lives like now?
