Intel's offices in Munich, Germany got raided today by the European Union to investigate claims it abused its market position. The investigation started after a complaint from AMD and a closed hearing will follow on March 11-12 in Brussels.
Chuck Mulloy, a spokesman for Intel, said the regulators raided the company's office in Munich, Germany.
Mr Mulloy said Intel was co-operating with the investigators.
Intel has been accused of trying to abuse its dominant market position by selling its products below cost price and making cash payments to customers.
"I can confirm that there has been a raid on our offices in Munich," Mr Mulloy said.
"As is our normal practice, we are co-operating with authorities," he added.
The European Commission has yet to name Intel, but confirmed that officials had carried out "unannounced inspections" at the premises of a chipmaker.
Commission spokesman Jonathan Todd said it had reason to believe the firm in question had violated European laws on restrictive business practices.
A number of Intel's main suppliers have also had their offices visited by inspectors.
