Glencore PLC on Friday said it was informed by the Office of the Attorney General of Switzerland that a criminal investigation has been opened against the company.

According to the company, the AG's office said it "opened a criminal investigation into Glencore International AG for failure to have the organizational measures in place to prevent alleged corruption in the Democratic Republic of Congo currently under investigation by the OAG."

Glencore said it would cooperate with the investigation.

In December, The Wall Street Journal reported the U.K.'s Serious Fraud Office was "investigating suspicions of bribery 'in the conduct of business by the Glencore group of companies, its officials, employees, agents and associated persons.'"

In July 2018, The Wall Street Journal reported Glencore said it "received a subpoena from U.S. authorities related to compliance with American corruption and money-laundering laws at its operations in Congo, Nigeria and Venezuela."
