A US-based Chinese workers’ rights organisation has claimed that a factory worker at a firm that produces Apple’s iPhones in China, died after jumping from a building on Saturday.

China Labor Watch (CLW) said that Li Ming, 31, jumped to his death from a building in the city of Zhengzhou, in the east-central Chinese Henan province, where he had been working for Foxconn.

The death has triggered comparisons with a wave of suicides in 2010 and 2011 at Foxconn factories in China amid concerns over working conditions.

CLW posted video footage that it said showed Mr Li, who the organisation claimed was was working for Foxconn through an agency, lying lifelessly on the ground after his leap. The footage, seemingly filmed from a nearby high-rise building, shows a body lying in the snowy ground, as four people stand nearby.

CLW said that it had spoken to Mr Li’s father, but that it was still not clear why he had jumped from the building. The organisation told The Telegraph that he had been working for Foxconn for two months and lived in factory dormitories.

Foxconn’s spokesperson did not respond to messages asking for further information about the incident.
