The boss of a Chinese toy manufacturing company involved in a Mattel recall after its products were found to contain excessive lead levels has hanged himself, Chinese media reported on Monday.

Zhang Shuhong, a Hong Kong businessman in his 50s and boss of the Lida Toy Company in the southern province of Guangdong, was found dead in his factory workshop on Saturday, the semi-official Southern Metropolitan Daily said.

About 1.5 million preschool toys made by Lida Toy, a Foshan-based contract manufacturer for Mattel Inc.'s Fisher-Price unit, were recalled across the globe by the US company last week.

Lida was not immediately available for comment. Calls to its factory went unanswered.

The recalled toys made for Mattel's Fisher-Price unit include popular preschool characters such as Elmo and Big Bird and dozens of other items. The case was the latest in a deluge of product safety scares that have tainted the "made-in-China" brand.

Lead paint has been linked to health problems in children, including brain damage. China's quality watchdog had banned Lida from exporting its goods. - Reuters
