American computer corporation Intel has been raided by European Commission authorities as part of investigations into possible antitrust violations. From its home base in Santa Clara, California, the company said it was cooperating fully and believed its practices were fair and lawful. It is currently fighting lawsuits in the U.S. and Japan. Smaller rival Advanced Micro Devices has long complained of unfair play. It alleges that Intel has used threats and kickbacks to illegally build up the world’s top computer chip business. The raids were said to include installations in England and Germany. National competition authorities were also inspecting other IT firms manufacturing or selling computers.
