China: 'GSK had bribery network'

Police in China have said British pharmaceuticals company GlaxoSmithKline made "illegal" transfers, as they released details of an investigation into bribery allegations.

Four senior Chinese executives from GSK have been held, said Gao Feng, head of the economic crimes investigation unit.

He said GSK had transferred as much as 3bn yuan ($489m; £323m) to travel agencies and consultancies since 2007.

GSK has said it has not found any evidence of corruption.
