A tenth employee of iPhone-maker Foxconn jumped to his death late on Wednesday, just hours after the company's chairman promised to make life better for employees at the sprawling production site in southern China.Skip related content

The company did not give details of the death but China's official Xinhua news agency reported on Thursday that an initial police investigation indicated the 23-year-old man from northwest China had committed suicide by jumping from a seventh floor dormitory balcony.

The spate of deaths has thrown a spotlight on the labour practices of Foxconn, a unit of Taiwan's Hon Hai Precision Industry, whose clients include Apple, Hewlett Packard and Sony Ericsson.

Apple and other clients have said they are investigating working conditions at Foxconn, which has some 420,000 employees at its base in Shenzhen and has come under fire for its secretive corporate culture.

Workers live inside the factory complex and churn out products for the world's leading computer and phone companies in round-the-clock shifts.

Taipei-based Hon Hai spokesman Arthur Huang confirmed the tenth death but denied reports on three Taiwan TV stations that another person, a young woman, had also jumped late on Wednesday, surviving with serious injuries.

Just hours before the latest reports, the usually media shy Foxconn Chairman Terry Gou had opened the company's sprawling facilities in Shenzhen to reporters and vowed to take sweeping action to prevent more deaths.

Gou made another trip back to the plant on Thursday following the Wednesday media tour. Pictures on Taiwan TV stations showed him boarding his private jet.
