On May 21, the DOJ announced criminal antitrust charges filed in the U.S. District Court for the Eastern District of Michigan against one current and one former executive of a Japanese manufacturer of spark plugs, standard oxygen sensors and air fuel ratio sensors. These charges follow a guilty plea by the manufacturer itself to related charges late last year, pursuant to which the manufacturer paid a $52.1 million criminal fine. According to the press release, the DOJ so far has charged 55 individuals in the ongoing investigation, and has secured guilty pleas or agreements to plead guilty from 35 corporations. Criminal fines from the investigation now total more than $2.5 billion.
