A federal judge in Detroit Friday signed off on what could be one of the last big developments in the Volkswagen diesel emissions scandal, ordering the German maker to pay a $2.8 billion criminal penalty negotiated as part of a settlement with the U.S. Justice Department last January. 

The ruling now brings to around $30 billion the costs VW will incur after being caught rigging two of its diesel engines to pass U.S. emissions tests — a figure that includes the price of buying back almost 500,000 vehicles sold in the country. Meanwhile, seven current and former Volkswagen employees have been charged with crimes connected to the scandal, while an investigation continues in Germany. NBC News
