GlaxoSmithKline (GSK ) has acknowledged that some senior employees in the firm were allegedly involved in a bribing scandal of doctors prescribing the firm's drugs in China.
According to the BBC, senior executives in GSK's China office appeared to have been using travel agencies to bribe government officials, doctors and hospitals in order to boost sales and prices of their drugs.
GSK is now co-operating with a Chinese investigation into the probe and several GSK employees have been detained by the Chinese police, the report added.
GSK's British head of finance in China, Steve Nechelput, has been subjected to a travel ban since the end of June.
