Senior executives at GlaxoSmithKline in China are facing a criminal investigation over accusations of bribery.
The Ministry of Public Security said they are being investigated for bribery and tax-related violations.
The BBC reports they are accused of offering bribes to officials and doctors to boost sales.
GSK said that it had found no evidence of bribery or corruption in China.
"We are willing to co-operate with the authorities in this inquiry," the company said in a statement.
The Ministry of Public Security said in a statement that police had questioned some of the suspects, and they had confessed.
It accused the company of bribing government officials and doctors, as well as overstating tax receipts.
"The case involves many people, the duration of time is long, the amount of money involved is huge and the criminal activities are malicious," the ministry said.
GSK is Britain's largest pharmaceutical company.
